When mass of body is doubled, the kinetic energy of body will be

A

half

B

doubled

C

one-fourth

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
we know that
Kinetic energy (KE) ` = (1)/(2) mv^(2)`
When m. = 2 m
(KE). `= (1)/(2) ( 2 m ) v^(2) = 2 xx (1)/(2) m v^(2)`
(KE). = 2 (KE)
