Question

If the momentum of a body increases by 0.01%,
its kinetic energy will increase by
(a) 0.01% (b) 0.02%
(c) 0.04% (d) 0.08%

Answer 1

Answer: The Correct answer is option (B) 0.02%

Explanation:

The explanation for the above answer is as follows :-

The relationship between energy and momentum can be described as Kinetic  energy(E) being directly proportional to the twice the increase in the percentage(P), provided mass(m) of the body remains constant.

It can be described by the following formula :-

E∝P2 (if m = constant) Percentage increase in E = 2(Percentage increase in P)                                        = 2 × 0.01% = 0.02%
