Vedclass · Answer

(D) When objects are dropped from the same height,they undergo free fall under the influence of gravity.According to the equations of motion,the acceleration of an object in free fall is independent of its mass and is equal to the acceleration due to gravity,$g$.Since both spheres are dropped from the same height and are at the same position ($1\, m$ above the ground),they have the same velocity.However,momentum $(p = mv)$,kinetic energy $(K = \frac{1}{2}mv^2)$,and potential energy $(U = mgh)$ all depend on the mass of the object.Since the masses are different ($2\, kg$ and $4\, kg$),their momentum,kinetic energy,and potential energy will be different.Therefore,the only quantity that remains the same for both spheres is their acceleration,which is $g$.

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
