Expo: WAEC GCE Physics Practical Questions and Answers 2022/2023 – Complete Solutions

The WAEC GCE Physics practical questions and answers are now available here on schoolisle. In this article I will give you free access to all you need with regards to this examination. I will give you free access to the physics past, sample and possible questions and answers. This is to enable you see how the GCE exam for this year will look like.

Bear in mind that every single procedure is awarded marks. So, ensure you do not skip any step while reporting and presenting your alternative to practical results. And do not forget to remember that the units are very important.

The Physics Practical question paper will consist of three areas and general Physics questions namely:

  1. Optics
  2. Electricity
  3. Mechanics

You will be expected to take your readings from an alternative to practical experiment, take readings and tabulate your values, plot graph, state precautions to be taken during the experiment, and report observation.

Today’s WAEC GCE Physics Practical Questions and Answers


Pls Tabulate:









Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity usually means relative density with respect to water.


Given volume of solid immersed

Vsi =1/2*30cm³


Density of liquid (water)ew= 1g/cm³

Acceleration due to gravity, g = 10m/s²

Upthrust, U= eVsi g

U= 1000*(15*10^-6)*10



Weight of solid =mg

=EsVs g

given: Es=2.4g/cm³ (2400kg/m³)

Vs=30cm (30*10^-6 m³)


Weight, w=30*10^-6*2400*10



Reading on spring balance =W-U





Tabulate pls:

S/n: 1,2,3,4,5,6

R/ohms: 0.00,1.00,2.00,3.00,4.00,5.00

I/A: 3.00,1.00,0.60,0.45,0.35,0.25

P=(E/I) V ohms^-1: 0.500,1.500,2.500,3.333,4.286,6.000


s=Y1-Y2/X2-X1 = 4-2/3.6-1.5




C = 0.5ohm




-I ensured that the circuit is open after each reading to maintain the E.M.F of the battery

-I ensured that the Zero Error of the Ammeter is checked and noted


V = 4.5v

R = 4ohms

I = 0.9A

V = I(R+r)

where r = internal resistance

4.5 = 0.9(4+r)

.:. 4+r = 4.5/0.9

4+r = 5

r = 5-4

= 1 ohm.

DISCLAIMER: The questions and answers above are not for the nov/dec examination. Instead, they are GCE past questions means for you to practice.

You are provided with two retort stands, two metre rules, pieces of thread and other necessary apparatus. (i) Set up the apparatus as illustrated above ensuring that the strings are permanently 10cm from either end of the rule.

(ii) Measure and record the length L = 80cm of the two strings.

(iii) Hold ends of the rule and displaces the rule slightly, then release so that it oscillates about a vertical axis through its centre.

(iv) Determine and record the time t for 10 complete oscillations. (v) Determine the period T of oscillations.

(vi) Evaluate log T and log L. (vii) Repeat the procedure for four other values of L = 70cm, 60cm, 50cm, and 40cm.

(viii) Tabulate your readings.

(ix) Plot a graph with log T on the vertical axis and log L on the horizontal axis.

(x) Determine the slope, s and the intercept, e on the vertical axis, of the graph.

(xi) State two precautions taken to ensure accurate results.

(b)(i) Define simple harmonic motion

(ii) Determine the value of L corresponding to t = 12s from the graph in 1 (a).


NOTE: please note that then answers below are the 2020 Nov/Dec answers. The 2022 November/December answers will soon be posted. Save this page and visit later for more answers.

Practical answers


-The first condition is that the net force on the object must be zero for the object to be stable

-If net force is zero, then net force along any direction is zero.

1bii) : (i) Magnitude of force applied.

(ii) Distance of line of action of the force from the axis of rotation.

SPECIFIC HEAT CAPACITY: of a substance is defined as the quality of heat supplied or required to raise the temperature of a unit mass of 1kg through a unit rise in the temperature of 1kelvin.(K)

3a.( IX.)

1. The reading should be taken when the meter is steady.

2. Large current or voltage must not be passed into the meter because it might damage it.

3. The calorimeter must be properly lagged to prevent heat loss.

Choose any 3

The truth about the Jan/Feb GCE Physics practical examination

Some people do ask “how do they calculate our marks during exams?“. Now, you have to note this: Your practical, objective and theory exams are computed together to give your grade. This simply means that you cannot take one exam and leave the rest behind else you will definitely fail.

You need to take all your papers serious in order to acquire the needed points. One way to begin with is to start reading the physics past questions and answers.
