A bullet fired from a gun. As a result the gun recoils the mass of the gun is 100 times the mass of the bullet. The ratio of the kinetic energies of the bullet and the gun will be

A

`10^4 : 1`

B

`100 : 1`

C

`1 : 100`

D

` 1 : 1`

Text Solution

Verified by Experts

The correct Answer is:

B

`K=P^2/(2m) `
`implies KE prop 1/m`
`implies ((KE)_1)/((KE)_2)=100/1 =m_2/m_1 = 100:1`
