Two masses of $1 \,gm$ and $4 \,gm$ are moving with equal kinetic energies. The ratio of the magnitudes of their linear momenta is
$4:1$
$\sqrt 2 :1$
$1:2$
$1:16$
Two masses of $1 \,gm$ and $4 \,gm$ are moving with equal kinetic energies. The ratio of the magnitudes of their linear momenta is
$P = \sqrt {2mE} .$ If $E$ are same then $P \propto \sqrt m $
$⇒$ $\frac{{{P_1}}}{{{P_2}}} = \sqrt {\frac{{{m_1}}}{{{m_2}}}} = \sqrt {\frac{1}{4}} = \frac{1}{2}$
