A block released from rest from the top of a smooth inclined plane of angle θ1 reaches the bottom in time t1. The same block released from rest from the top of another smooth inclined plane of angle θ2, reaches the bottom in time t2. If the two inclined planes have the same height, the relation between t1 and t2 is
