The kinetic energy of a body becomes 4 times its initial value. The new lines momentum will be

A

same as the initial value

B

twice of the initial value

C

four times of the initial value

D

eight times of the initial value

Text Solution

Verified by Experts

The correct Answer is:
B
`p = sqrt(2mE)` when `E. = 4E = p. = sqrt(2m xx 4E) = 2p`
