A ball P is dropped vertically and another ball Q is thrown horizontally with the same velocities from the same height and at the same time. If air resistance is neglected, then

Ball P reaches the ground first

Ball Q reaches the ground first

Both reach the ground at the same time

The respective masses of the two balls will decide the time
