A bullet of mass 50 gram is fired from a 5 kg gun with a velocity of 1 km/s . the speed of recoil of the gun is

A

5 m/s

B

1 m/s

C

0.5 m/s

D

10 m/s

Text Solution

Verified by Experts

The correct Answer is:
D
According to conservation of momentum
`m_(B) v_(B) + m_(G) v_(G) = 0 rArr v_(G)= -(m_(B) v_(B))/(m_(G))`
`v_(G)= (-50 xx 10^(-3) xx 10^(3))/(5)= - 10 m//s`
