2.Motion in Straight Line
easy

Two spheres of same size one of mass $2\, kg$ and another of mass $4\, kg$ are dropped simultaneously from the top of Qutab Minar(height $= 72\,m$). When they are $1\,m$ above the ground, the two spheres have the same

A

momentum

B

kinetic energy

C

potential energy

D

acceleration

(AIIMS-2006)

Solution

Since their masses are different they will have different momentum, kinetic energy and potential energy. But their acceleration will be same which will be equal to $g$
