A ball \( \mathrm{P} \) is dropped vertically and another ball \( \mathrm{Q} \) is thrown horizontally with the same velocities from the same height and at the same time. If air resistance is neglected, then
(1) Ball P reaches the ground first
(2) Ball Q reaches the ground first
(3) Both reach the ground at the same time
(4) The respective masses of the two balls will decide the time
