Question

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

Answer 1

Answer:

Hey there!! I am here to give you the answer....

Explanation:

 kinetic energy , KE = P²/2m

              here p= momentum

                      m= mass of the object

if p is increased by 10% i.e., 0.1 times KE will inceases to by 100%

so the kinetic energy will become twice the original.

so option 1) 20% is the correct option.

Hope it helps you.
