A bullet weighing 200 g is fired horizontally with a velocity of 25 m/sec from a gun carried on a carriage which together with the gun weighs 100 kg. The velocity of recoil of the gun, will be

Statement I When a gun is fired, i.e. it placing pushes back with much less velocity than the velocity of the bullet.
Statement II Velocity of the recoiling gun is less because the gun is much heavier than bullet.
According to the Principle of conservation of momentum when the gun is fired, momentum of gun and bullet system remains constant.

A

Both the statements are individually true and statement II is the correct explanation of statement I

B

Both the statements are individually true but statement II is not the correct explanation of statement I

C

Statement I is true, but statement II is false

D

Statement I is false, but statement II is true

Five friends went for a trip where each carried a certain number of apples with them. The number of apples carried by C was 1 less than that by D, which was 5 more than the number of apples carried by E. The total number of apples carried by A and B both was equal to the average number of apples carried by C, D and E. If D carried more apples than B and they together carried 14 apples, which of the following is a possible value of the apples carried by A?

A
