- Covers fewer topics but focuses on fundamental concepts.
- Less emphasis on mathematical derivations.
- No practical paper (only a written paper for practical assessment).
📌 H2 Physics (For students who need in-depth knowledge for STEM courses)
- More advanced and requires strong conceptual understanding.
- Includes mathematical derivations & practical assessments.
- Covers mechanics, waves, electromagnetism, quantum physics, and more.

1. Difficult Questions from Past Papers with Model Answers
Question 1: Electromagnetic Induction
Source: Cambridge A-Level H2 Physics Paper 3, 2018
Question:
A rectangular coil of NN turns, length ll, and width ww is rotated at a constant angular velocity ω\omega in a uniform magnetic field BB about an axis perpendicular to the field. The plane of the coil is initially perpendicular to the magnetic field.
(a) Derive an expression for the electromotive force (emf) induced in the coil as a function of time.
(b) If N=50N = 50, l=0.1 ml = 0.1 \, \text{m}, w=0.05 mw = 0.05 \, \text{m}, B=0.2 TB = 0.2 \, \text{T}, and ω=100 rad/s\omega = 100 \, \text{rad/s}, calculate the maximum value of the induced emf.
Model Answer:
(a) The magnetic flux Φ\Phi through the coil at any time tt is given by:
Φ=NBAcos(ωt)\Phi = NBA \cos(\omega t)
where A=lwA = lw is the area of the coil. The induced emf E\mathcal{E} is:
E=−dΦdt=−ddt[NBAcos(ωt)]=NBAωsin(ωt)\mathcal{E} = -\frac{d\Phi}{dt} = -\frac{d}{dt}[NBA \cos(\omega t)] = NBA\omega \sin(\omega t)
(b) The maximum induced emf Emax\mathcal{E}_{\text{max}} occurs when sin(ωt)=1\sin(\omega t) = 1:
Emax=NBAω=(50)(0.2 T)(0.1 m×0.05 m)(100 rad/s)=5 V\mathcal{E}_{\text{max}} = NBA\omega = (50)(0.2 \, \text{T})(0.1 \, \text{m} \times 0.05 \, \text{m})(100 \, \text{rad/s}) = 5 \, \text{V}
Question 2: Quantum Physics
Source: Cambridge A-Level H2 Physics Paper 1, 2018
Question:
The work function of a metal is 2.0 eV2.0 \, \text{eV}. Light of wavelength 400 nm400 \, \text{nm} is incident on the metal surface. Determine whether photoelectric emission occurs, and if so, calculate the maximum kinetic energy of the emitted electrons.
Model Answer:
The energy EE of the incident photons is:
E=hcλ=(6.63×10−34 Js)(3.0×108 m/s)400×10−9 m=4.97×10−19 JE = \frac{hc}{\lambda} = \frac{(6.63 \times 10^{-34} \, \text{Js})(3.0 \times 10^{8} \, \text{m/s})}{400 \times 10^{-9} \, \text{m}} = 4.97 \times 10^{-19} \, \text{J}
Converting this energy to electron volts:
E=4.97×10−19 J1.6×10−19 J/eV≈3.1 eVE = \frac{4.97 \times 10^{-19} \, \text{J}}{1.6 \times 10^{-19} \, \text{J/eV}} \approx 3.1 \, \text{eV}
Since 3.1 eV>2.0 eV3.1 \, \text{eV} > 2.0 \, \text{eV}, photoelectric emission occurs. The maximum kinetic energy KmaxK_{\text{max}} of the emitted electrons is:
Kmax=E−Work function=3.1 eV−2.0 eV=1.1 eVK_{\text{max}} = E – \text{Work function} = 3.1 \, \text{eV} – 2.0 \, \text{eV} = 1.1 \, \text{eV}

Practice Solution:
The angular frequency ω\omega is:
ω=2πT=2π2 s=π rad/s\omega = \frac{2\pi}{T} = \frac{2\pi}{2 \, \text{s}} = \pi \, \text{rad/s}
Since the mass starts at maximum displacement, the displacement function is:
x(t)=Acos(ωt)=0.1 m×cos(πt)x(t) = A \cos(\omega t) = 0.1 \, \text{m} \times \cos(\pi t)
Question 4: Electric Fields
Two point charges, +2 μC+2 \, \mu\text{C} and −3 μC-3 \, \mu\text{C}, are placed 0.5 m0.5 \, \text{m} apart in a vacuum. Calculate the magnitude and direction of the electric field at the midpoint between the charges.
Practice Solution:
The electric field due to a point charge qq at a distance rr is:
E=k∣q∣r2E = \frac{k|q|}{r^2}
At the midpoint, each charge is 0.25 m0.25 \, \text{m} away. The electric fields due to each charge are:
E+=(8.99×109 Nm2/C2)(2×10−6 C)(0.25 m)2=2.88×105 N/CE_{+} = \frac{(8.99 \times 10^9 \, \text{Nm}^2/\text{C}^2)(2 \times 10^{-6} \, \text{C})}{(0.25 \, \text{m})^2} = 2.88 \times 10^5 \, \text{N/C}
E−=(8.99×109 Nm2/C2)(3×10−6 C)(0.25 m)2=4.32×105 N/CE_{-} = \frac{(8.99 \times 10^9 \, \text{Nm}^2/\text{C}^2)(3 \times 10^{-6} \, \text{C})}{(0.25 \, \text{m})^2} = 4.32 \times 10^5 \, \text{N/C}
The fields are in opposite directions (away from the positive charge and toward the negative charge). The net electric field EnetE_{\text{net}} at the midpoint is:

B. Identify and Correct the Mistakes in These Questions 🔍
Each question below contains an error. Identify the mistake (wrong solution, incorrect math calculation, wrong unit, or conceptual mistake) and correct it.
Question 1: Incorrect Unit Application
A force of 10 N is applied to an object with a mass of 5 kg. What is the acceleration in m/s?
Mistake: The correct unit for acceleration is m/s2m/s^2, not m/sm/s.
Corrected Solution:
F=maF = ma ⇒a=Fm=105=2\Rightarrow a = \frac{F}{m} = \frac{10}{5} = 2 m/s2m/s^2
Question 2: Wrong Formula Application
A 2 kg ball is dropped from a height of 5 m. What is its velocity just before it hits the ground? (Ignoring air resistance)
Given: m=2kg,h=5m,g=9.81m/s2m = 2kg, h = 5m, g = 9.81 m/s^2
Incorrect Solution: v=mgh2v = \frac{mgh}{2}
Mistake: The formula used is incorrect. The correct equation is from energy conservation: mgh=12mv2mgh = \frac{1}{2}mv^2.
Corrected Solution: v=2gh=2(9.81)(5)=9.9v = \sqrt{2gh} = \sqrt{2(9.81)(5)} = 9.9 m/s
Question 3: Wrong Calculation Using a Formula
A circuit has a current of 2 A and a resistance of 4 Ω. What is the voltage across the resistor?
Incorrect Solution: V=I+R=2+4=6VV = I + R = 2 + 4 = 6V
Mistake: The formula for Ohm’s Law is V=IRV = IR, not V=I+RV = I + R.
Corrected Solution: V=2×4=8VV = 2 \times 4 = 8V
Question 4: Conceptual Mistake in Free Fall Motion
A student states that a heavier object falls faster than a lighter object due to greater weight.
Mistake: In a vacuum, objects fall at the same acceleration regardless of mass.
Corrected Explanation: All objects experience the same acceleration due to gravity (9.81 m/s²), assuming negligible air resistance.
C. Experimental Error Identification & Correction 🧪
Experiment 1: Measuring Acceleration Due to Gravity
A student drops a ball and measures the time taken to fall using a stopwatch. The calculated acceleration is 8.5 m/s².
Possible Errors:
- Human reaction time affects stopwatch accuracy.
- Air resistance might slightly reduce acceleration.
Correction:
- Use a light gate or electronic timer for more precise measurements.
Experiment 2: Investigating Hooke’s Law
A student measures the extension of a spring by applying different weights but does not record the initial length of the spring.
Mistake: Without the initial length, the extension cannot be accurately calculated.
Correction: Always measure and record the spring’s original length before applying force.
