1.	A block released from rest from the top of a smooth inclined plane of angle 30^@ reaches the bottom in time t_1. The same block released from rest from the top of another smooth inclined plane of angle 60^@, reaches the bottom in time t_2. If the two inclined planes have the same height, the relation between t_1 and t_2 is
Answer» `(t_2 )/(t_1) =1/2` `(t_2)/(t_1)=1` `(t_2)/(t_1) =(1)/( SQRT(3))` `(t_2)/(t_1) =2` SOLUTION :`(t_2)/(t_1) =(1)/( sqrt(3))`
