The steps for all the calculations are the same for related questions. Study this page intensively till you enter the hall for your examination.

1. A man walks 1km due east and then due north. His displacement is

A. √2km N 45 degrees E

B. √1km N 30 degrees E

C. √1km N 15 degrees E

D. √2km N 60 degrees E


Explanation: Draw four cardinal points and label them N, E, S, and W, and draw a horizontal line 1km (not to scale) due east and 1km due north. Join the line from the top to the bottom as shown in the diagram below:

JAMB Physics solution

R^2 = 1^2 + 1^2

R = √(1+1)

R = √2

Solving for Tita implies

tan^-1(1/1) = 45 degree.

2. The density of the oil was 0.9 gcm^-3 before frying. If the density was 0.6 gcm^-3 after frying, assuming no loss of oil due to spilling, its new volume was

A. 360 cm^3

B. 600 cm^3

C. 240 cm^3

D. 800 cm^3


Explanation: Since there was no loss of oil due to spilling, Density x Volume = constant

D1V1 = D2V2

0.9V1 = 0.6V2

V2 = 0.9 x 400/0.6

V2 = 600 cm^3

3. Which of the following is true of an electrical charge?

A. Positive charge means deficit electrons

B. Negative charge means the excess of electrons

C. Electric current means the movement of electrons

D. All of the above.


4. Natural radioactivity consists of the emission of

A. alpha particles and beta rays

B. alpha particles and X-rays

C. alpha, beta rays, and gamma rays

D. gamma rays and X-rays


5. Which of the following does NOT describe the image formed by a plane mirror?

A. Erect

B. Laterally inverted

C. Same distance from the mirror as the object

D. Magnified


JAMB physics solution

6. What is the resultant resistance of the circuit given above?

A. 8 ohms

B. 11 ohms

C. 4 ohms

D. 3.6 ohms


Explanation: Calculate the two resistors in parallel and then calculate the series connection.

The formula for a resistor in parallel, 1/ R = 1/R1 + 1/R2…

The formula for a resistor in series, R = R1 + R2

The two resistors in parallel = 2 ohms and 2 ohms

this implies: 1/R = 1/2 + 1/2 = 1

R = 1 ohm

This 1 ohm resistor becomes in series with the 3 ohms and 4 ohms resistors

The resultant resistor of the circuit, Reqv. = 3+1+4 = 8 ohms.

7. Which of the following best describes the energy changes that take place when a steam engine drives a generator that lights a lamp?

A. Heat->Light->Sound->Kinetic

B. Heat->Kinetic->Electricity->Heat and Light

C. Kinetic->Light->Heat->Electricity

D. Electricity->Kinetic->Heat->Light

7 Tips to Prepare for Jamb Exams

  1. Don’t make reading your hobby: A lot of people put reading as a hobby in their CV, they might be right because they have finished schooling. But “You” are still schooling, so reading should be a top priority and not a hobby. Read far and wide to enhance your level of aptitude
  2. Get Exams Preparation Materials: These involve textbooks, dictionaries, Babcock University Post UTME Past Questions and Answers, mock questions, and others. These materials will enhance your mastery of the scope of the exams you are expecting.
  3. Attend Extramural Classes: Register and attend extramural classes at your location. This class will help you refresh your memory and boost your classroom understanding and discoveries of new knowledge.
  4. Sleep when you feel like: When you are preparing for any exams, sleeping is very important because it helps in the consolidation of memory. Caution: Only sleep when you feel like it and don’t oversleep.
  5. Make sure you are healthy: Sickness can cause excessive feelings of tiredness and fatigue and will not allow you to concentrate on reading. If you are feeling as if you are not well, report to your parent, a nurse, or a doctor. Make sure you are well.
  6. Eat when you feel like it: During the exam preparation period, you are advised not to overeat, and to avoid sleep. You need to eat little and light food whenever you feel like eating. Eat more fruits, drink milk and glucose. This will help you enhance retention.
  7. Reduce your time on social media: Some people live their entire lives on Facebook, Twitter, WhatsApp, and Messenger chat. This is so bad and catastrophic if you are preparing for exams. Try and reduce your time spent on social media during this time. Maybe after the exams, you can go back and sleep in it.
