The Top 14 JEE Main Physics questions with answers are listed below, and students can practise them to get an idea of all the important topics of the subject:

Question 1. There is a mass of 100 grams at the end of a spring whose natural length, l0, is 20. The spring moves in a circular motion with the Ω of 5 rad/sec. Find the tension in the spring.

Answer- 0.75 N

Question 2. Two masses of 1 g and 4g move with equal kinetic energy. The ratio of the magnitudes of their momenta is

(a) 4: 1

(b) √2: 1

(c) 1: 2

(d) 1: 16

Answer: (c) 1: 2

Question 3. If the weight of an object on the Earth's surface is 400 N, then the weight of the same particle at a depth R/2 from the surface would be (R is the Earth's radius)?

a) 100 N

b) 300 N

c) 200 N

d) 250 N

Question 4.  If a machine is lubricated with oil

(a) the mechanical advantage of the machine increases

(b) the mechanical efficiency of the machine increases

(c) both its mechanical advantage and efficiency increase

(d) its efficiency increases, but its mechanical advantage decreases.

Answer: (b) When a machine is lubricated with oil, friction decreases. Hence, the mechanical efficiency of the machine increases.

Question 5. If the height of a tower used for LOS Communication is increased by 21%, then what Is the percentage change in the range?

Answer: 10%

Question 6. Two blocks of masses 10 kg and 4 kg are con­nected by a spring of negligible mass and placed on a frictionless horizontal surface. An impulse gives a velocity of 14 m/s to the heavier block in the direction of the lighter block. The velocity of the centre of mass is

(a) 30 m/s

(b) 20 m/s

(c) Ten m/s

(d) Five m/s

Answer: (c) 10 m/s

Question 7. A Block of Mass 100 gms is placed on a smooth surface and moves with an acceleration of a = 2x, then the change in Kinetic Energy can be given as (xn/10), find the value of n. 

Answer:  n = 2

Question 8. A piece of wood of mass 0.03 kg is dropped from the top of a 100-height building. At the same time, a bullet of mass 0.02 Kg is fired vertically upward, with a velocity of 100 m/s, from the ground. The bullet gets embedded in the wood. Then, the maximum height the combined system reaches above the top of the building before falling below is (g = 10 m/s).

Answer: (d) 40 m

Question 9. Length 20% increase, Area 4% decrease, changeR/R =?

Answer: 25

Question 10. An automobile travelling at 40 km/h can be stopped at a distance of 40 m by applying brakes. If the same automobile travels 80 km/h, what is the minimum stopping distance in metres (assuming no skidding)?

Answer: (c)160 m

(a) 2/5

(b) 3/2

(c) 3/5

(d) 2/3

Answer: (a) 2/5

Question 13. Two moles of an ideal monatomic gas occupy a volume V at 27 degree C. The gas expands adiabatically to a volume of 2V. Calculate (i) the final temperature of the gas and (ii) the change in its internal energy.

(a) (i) 198 K (ii) 2.7 kJ
