Here are 10 high-quality JEE Mains 2025 Physics

uestions that cOver various topics and are designed to

test your understanding of key concepts:

1. Aparticle of mass 1 kg is moving in a circular path of

radius 2 m with aconstant speed of 4 m/s. What is the

magnitude of the centripetal force acting on the

particle?

A) 4 N B) 8 N C) 12 N D) 16 N

  1. A ray of light passes from air into a glass slab of refractive index 1.5. If the angle of incidence is 45, what is the angle of refraction?

A) 20° B) 25° C) 30° D) 35°

  1. A wireof length 1 m and resistance 2 Qis connected

to a battery of emf 4 V. What is the current flowing

through the wire?

A) 1A B) 2 A C) 3 A D) 4 A

4. Ablock of mass 2 kg is placed ona horizontal surface. A

force of4 N is applied to the block. If the coefficient of

kinetic friction between the block and the surface is 0.2, what is the acceleration of the block?

A) 1 m/s^

B) 2 m/s^

C) 3 m/s^

D) 4 m/s^

5. Amagnetic field of strength0.1 Tis applied

perpendicular to a coil of 100 turns. If the area of the coil is O.1 m^2, what is the induced emf in the coil?

A) 1V B) 2 V C) 3 V D)4 V

A) 8 W B) 16 W C) 24 W D) 32 W

  1. Ablock of mass 5 kg is placed on a horizontal surface. A force of 10 Nis applied to the block at an angle of 30° with the horizontal. What is the acceleration of the block?

A) 1 m/s^ B) 2 m/s^ C) 3 m/s^

D) 4 m/s^

  1. A wave travels from one endof a string to the other

end in 2 seconds. If the length of the string is 1.5 m, what is

the speed of the wave?

A) 0.75 m/s B) 1.5 m/s C) 3 m/s

D) 4.5 m/s

Solutions:

1. Fc = (m x v^2) /r=8N

  1. sin(r) = (1/1.5) x sin(45), r=30°
    1. | = V/R= 2 A

4. a =(F- uN)/m=2 m/s

  1. 8 = N(do/dt) =2 V
  2. V= u+ at = 28 m/s

7.F= (f +f2) /(1- (fi xf2) /(fi + f2)) = 10 cm

8. P=I^2R = 16 W

  1. a =(Fcos -uN) /m=2 m/s^
    1. v =d/t=0.75 m/s
