From a building two balls A and B are thrown such that A is thrown upwards A and B downwards (both vertically). If v_A and v_B are their respective velocities on reaching the ground, then

1. their velocities depend on their masses
2. V_B > V_A
3. V_A = V_B
4. V_A > V_B

Answer

Using conservation of energy, that is potential energy at height h is equal to the KE at ground.

This implies, for object A,

m_Agh = (m_AV_A²)/2

V_A = √2gh

Similarly

V_B = √2gh

The correct option is C.
