If kinetic energy of a body is increased by

300 \%

than percentage change in momentum will be:

Options

A $100 \%$
B $150 \%$
C $265 \%$
D $73.2 \%$

Correct answer

A. $100 \%$

Step-by-step solution

Here

P_1=\sqrt{2 m E_1}

and

P_2=\sqrt{2 m E_2}

\begin{aligned} P^{\prime} & =\sqrt{2 m\left(E+\frac{300}{100} E_1\right)} \\ & =\sqrt{2 m 4 E_1} \\ & =2 P_1 \end{aligned}

$$
