If a lighter body (mass ${M_1}$ and velocity ${V_1}$) and a heavier body (mass ${M_2}$ and velocity ${V_2}$) have the same kinetic energy, then
${M_2}{V_2} < {M_1}{V_1}$
${M_2}{V_2} = {M_1}{V_1}$
${M_2}{V_1} = {M_1}{V_2}$
${M_2}{V_2} > {M_1}{V_1}$
A particle of mass $'m'$ and charge $'q'$ is accelerated through a potential difference of $'V'$ volt. Its energy is
The mass of two substances are $4gm$ and $9gm$ respectively. If their kinetic energies are same, then the ratio of their momenta will be
A $4 \,kg$ mass and a $1\, kg$ mass are moving with equal kinetic energies. The ratio of the magnitudes of their linear momenta is
Two bodies of masses m and $2m$ have same momentum. Their respective kinetic energies ${E_1}$ and ${E_2}$ are in the ratio
