Momentum of a particle is increased by 2% without change in its mass. Find the percentage of change in its kinetic energy.

Easy

A

$40 %$
B

$4 %$
C

$44 %$
D

12%

Solution

$\begin{array}{r} K = \frac{p^{2}}{2 m} \\ or K \propto p^{2} \end{array} % c h a n g e i n K = 2 (% c h a n g e i n p) = 2 (2 %) = 4 %$
