General Comments on Physics Paper 2, May/June 2014:
The paper was comparable in scope and standard to previous years. Questions were clearly framed in simple language, accessible to candidates. Rubrics were clear, and marking schemes were detailed and easy to follow. The exam emphasized the psychomotor aspect more prominently, while cognitive and affective domains met acceptable standards.
Candidates performed better compared to previous years, with a candidate population of 665,669 achieving a raw mean score of 16 and a standard deviation of 8.77. This contrasts with a raw mean score of 13 and a standard deviation of 8.77 in the May/June 2013 WASSCE, which had a candidate population of 636,924.
Physics Question 1:
A particle is projected horizontally at 10 m/s from the top of a tower 20 m high. Calculate the horizontal distance traveled by the particle when it hits the level ground.
[g = 10 m/s^2]
Observation:
This question was attempted well by most candidates, as it is a familiar topic. However, some candidates mistakenly used "2g" instead of simply "g". Nevertheless, the majority of candidates correctly applied the formula, although a few struggled with completing the arithmetic calculations.
Question 2
A particle is projected horizontally at 15 m/s from a height of 20 m. Calculate the horizontal distance covered by the particle just before hitting the ground.
[g = 10 m/s2]
Observation:
Many candidates provided acceptable responses, resulting in high performance. However, a few failed to apply the appropriate formula.
Expected Answer:
Let R represent the horizontal distance covered at time, t.
We know:
h = (1/2)gt2
Given:
20 = (1/2) × 10 × t2
Solving for t:
t = 2 seconds
Then, we use the formula:
R = ut
R = 15 × 2
R = 30 meters.
Physics Question 3
Explain why mercury does not wet glass while water does.
Observation:
Good responses were given by many candidates. Few fumbled due to their failure to relate cohesion and adhesion forces with molecules of mercury and glass.
Expected Answers:
Mercury does not wet glass because (force of) cohesion/attraction of mercury molecules is greater than (force of) adhesion/attraction between glass and mercury molecules.
Water wets glass because (force of) adhesion/attraction between glass and water molecules is greater than (force of) cohesion/attraction of water molecules.
Physics paper 2 Question 4
Explain what is meant by cations.
Draw and label an electrolytic cell.
Observation:
(a) Many candidates gave an incomplete explanation. Many stopped at "cations are positive ions" and not all positive ions are cations.
(b) Many candidates were unable to present a diagram that shows a cathode and an anode dipped in an electrolyte or they drew wrong diagrams connecting external components to an otherwise correct set-up.
Very poor performance was registered by candidates.
Expected Answers:
(a) Cations – are positive ions that are attracted to the cathode (during electrolysis).
(b) Diagram
Correct diagram/sketch: labeling cathode, anode, and electrolyte.
Question 5 – physics Paper 2
State three methods of polarizing an unpolarized light.
Observation:
This question on polarization was very popular among the candidates and their responses were quite commendable.
Physics Question 6
State Faraday’s second law of electrolysis.
An electric charge of 9.6 x 10^4 C liberates 1 mole of substance containing 6.0 x 10^23 atoms. Determine the value of the electronic charge.
Observation:
In part (a), many candidates were able to state the law correctly. Candidates’ performance in part (b) was poor due to lack of knowledge of the appropriate formula.
Expected Answers:
(a) If the same quantity of electricity is passed through different voltameters/electrolytes connected in series the masses of the substances liberated/deposited during electrolysis is (directly) proportional to their chemical equivalents.
OR The mass of an element deposited/liberated during electrolysis is (directly) proportional to the chemical equivalent of the element.
(b) Let e represent the electronic charge.
e = Faraday’s constant / Avogadro’s number
e = 9.6 x 10^4 / 6.0 x 10^23
e = 1.60 x 10^-19 C

WAEC PHYSICS ESSAY OR THEORY ANSWERS FOR 2024:
2b.
The energy stored in a stretched wire, E, can be calculated using the formula:
E = (1/2) × Y × A × e2
Where:
- E represents the energy stored in the wire.
- Y is the material's stiffness, measured by its Young's modulus.
- A denotes the wire's cross-sectional area.
- e is the extension or change in length of the wire from its initial length.
You can see that Young's modulus and cross-sectional area directly influence the energy stored in the wire, which is proportional to the square of the extension.
