Question
Assertion : If two objects of different masses have same momentum, the lighter body possess greater velocity.
Reason : For all bodies momentum always remains same.
✓

Answer

(c) According to definition of momentum$P=m v$ if $P=$ constant then $m v=$ constant or $v \propto \frac{1}{m}$.As velocity is inversely proportional to mass, thereforelighterbody possess greater velocity.
