Question

An object takes time t1 to reach the bottom, when it is placed on the surface of a smooth inclined plane of inclination theta. If same object takes time t2 to reach the bottom, when it is allowe to slide down a rough inclined plane of same inclination theta (u=coefficient of friction between object and inclined plane). The ratio of t1/t2 i
