1. The SI unit of electric field is:
- (A) N/C
- (B) C/N
- (C) J/C
- (D) V.m
Show answer
(A) N/C. Concept: Electric field is force per unit positive test charge. Formula: E = F / q ⇒ unit = newton / coulomb (N/C). Also E = −dV/dx ⇒ volt / metre (V/m); 1 N/C = 1 V/m. Steps: [E] = [F]/[q] = N / C Alternatively V/m = (J/C)/m = (N·m/C)/m = N/C ✓ Why others are wrong: - B) C/N is the reciprocal. - C) J/C is the volt — unit of potential, not field. - D) V·m is not a standard unit (V/m would be). Remember: Field = N/C = V/m; potential = J/C = V; flux = N·m²/C = V·m. Dimensions of E: MLT⁻³A⁻¹.
2. Two people, one of mass 100 kg and the other of mass 50 kg, stand facing each other on an ice-covered (essentially frictionless) pond. If the heavier person pushes on the lighter one with a force F, then
- (A) the force felt by the heavier person is (-1/2)F
- (B) the force felt by the person is -2F
- (C) the magnitude of the acceleration of the lighter person will be half of the magnitude of the acceleration of the heavier person
- (D) the magnitude of the acceleration of the lighter person will be twice the magnitude of the acceleration of the heavier person
Show answer
(D) the magnitude of the acceleration of the lighter person will be twice the magnitude of the acceleration of the heavier person. Correct answer: the magnitude of the acceleration of the lighter person will be twice the magnitude of the acceleration of the heavier person.
3. Which of the following concerning uniform circular motion is true?
- (A) The centrifugal force is the action-reaction pair of the centripetal force.
- (B) A satellite undergoing uniform circular motion is falling toward the center in a circular path.
- (C) The centripetal acceleration and velocity point in the same direction.
- (D) The velocity of the object in motion changes whereas the acceleration of the object is constant.
Show answer
(B) A satellite undergoing uniform circular motion is falling toward the center in a circular path.. Correct answer: A satellite undergoing uniform circular motion is falling toward the center in a circular path..
JEE (Engineering) Physics — FAQs
Is the JEE (Engineering) Physics mock test free?
Yes. All 6 Physics sets are free, need no signup, and give instant scores with a solution for every question.
How many Physics questions are there for JEE (Engineering)?
239 questions across 6 sets: 1 easy, 146 moderate and 92 hard.
Will I get the same questions again?
No. Each attempt draws a fresh random subset, shuffles the order and options, and prefers questions you have not seen on this device. The Surprise Set draws from the whole subject pool.
Can I choose difficulty and timer?
Yes — pick Easy, Moderate, Hard or Mixed, and choose no timer, 10 or 20 minutes, or the real exam pace.
