Two balls P (mass 50g) and Q (mass 200g) are dropped together from the roof of a building. Neglecting air resistance, which statement is correct?
(a) Q reaches the ground first because its greater weight makes it accelerate faster.
(b) Both balls reach the ground at different times but attain the same velocity.
(c) Both balls reach the ground together and with equal velocities.
(d) Both balls reach the ground together but Q has a greater velocity than P.
