A) Heavier mass possesses lesser\[K.E.\]
B) The masses of the two bodies are in the direct ratio of their velocities.
C) Lighter mass possesses less\[K.E.\]
D) Both [a] and [b]
Correct Answer: A
Solution :
Momentum of the heavy body\[=MV\] Momentum of the light body\[=mv\] The momenta are equal\[MV=mv\], \[\therefore \]\[\frac{M}{m}=\frac{v}{V}\] Masses are in the inverse ratio of velocities. So, heavier mass will possess less K.E.
