Question

4.if momentum of an object is increased by 10% then its kinetic energy will increase by-
(1) 20%
(2) 21%
(3) 40%
(4) 19%
​

Answer 1

Answer:

2) 21%

Explanation:

if 1 increases the momentum by 10% the kinetic energy will be naturally increased. So one can say that the KE will increase by 21%.

Answer 2

Answer:

option (2) 21%

this is the correct answer
