10. A block released from rest from the top of a smooth inclined plane of angle O, reaches the bottom in time t,. The same block released from rest from the top of another smooth inclined plane of angle 02, reaches the bottom in time tz. If the two inclined planes have the same height, the relation between t and tą is (a) 2 sin o, 1/2 (b) 2 = 1 tu (sin 02) sin , sin e (c) ta sin , t sine,

The same block released from rest from the top of another smooth inclined plane of angle theta_2 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

A block released from rest from the top of a smooth inclined plane of angle theta_1 reaches the bottom in time t_1 . The same block released from rest from the top of another smooth inclined plane of angle theta_2 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

A block released from rest from the top of a smooth inclined plane of angle of inclinatione, reaches the bottom in time t_(1) The same block, released from rest from the top of another smooth inclined plane of angle of inclination theta_(2) reaches the bottom in time ty. If the two inclined planes have the same height, the relation between t_(1) and t_(2) is :

A block released from rest from the top of a smooth inclined plane of inclination 45^(@) takes time 't' to reach the bottom . The same block released from rest , from top of a rough inclined plane of same inclination , takes time '2t' to reach the bottom , coefficient of friction is :

The same block, released from rest from the top of another smooth inclined plane of angle of inclination theta_(2) = 45^(@) reaches the bottom in time t_(2) . Time t_(1) and t_(2) are related as ( Assume that the initial heights of blocks in the two cases are equal ).
