Physics - W.E.P. Question with Solution | TestHub

$\because$ Relation between kinetic energy and momentum is ${\mathrm{p}}_1=\sqrt{2{\mathrm{mk}}_1}$ $\because$ Kinetic energy is increased by 4 times $\therefore {\mathrm{k}}_2=4{\mathrm{k}}_1$ Hence, ${\mathrm{p}}_2=\sqrt{2{\mathrm{mk}}_2}=\sqrt{2\mathrm{m}\left(4{\mathrm{k}}_1\right)}=2\sqrt{2{\mathrm{mk}}_1}$ or ${\mathrm{p}}_2=2{\mathrm{p}}_1$
