Your Ultimate Guide to JEE & NEET Question Solutions

A body of mass ${M_1}$ collides elastically with another mass ${M_2}$ at rest. There is maximum transfer of energy when

A

${M_1} > {M_2}$

B

${M_1} < {M_2}$

C

${M_1} = {M_2}$

D

Same for all values of ${M_1}$ and ${M_2}$

A body of mass ${M_1}$ collides elastically with another mass ${M_2}$ at rest. There is maximum transfer of energy when

 When $M_{1}=M_{2},$ velocity are exchanged. So total energy of $M_{1}$ is transfred to $M_{2}$
