Question

19.

If the kinetic energy of a body becomes four times of its initial value, then new momentum will-
(1) Become twice its initial value
[AFMC-98]
(2) Become three times, its initial value
(3) Become four times, its initial value
(4) Remains constant​

Answer 1

Answer:

1

Explanation:

Momentum P= (2mK)^1/2

Mass m is constant

So P is directly proportional to K^(1/2)

It means it becomes twice its initial value
