If we increase kinetic energy of a body $300%$ , then per cent increase in its momentum is

Options:

Answer:

Solution:

$p^{2} = 2 ME ∴ p \propto E ∴ \frac{p _{1}}{p _{2}} = \frac{E _{1}}{E _{2}} = \frac{E}{E + 3 E} = \frac{1}{2}$ $\Rightarrow p_{2} % Increase = 2 p_{1} = \frac{p _{2} - p _{1}}{p _{1}} \times 100$ $\Rightarrow \frac{2 p _{1} - p _{1}}{p _{1}} \times 100 = 100%$
