A long horizontal conveyer belt moves with a constant velocity of 8 m/*. Two blocks A and B each of mass 2 kg are placed gently on the belt with B on A. cofficient of kinetic friction b/w A and belt is 0.1. There is no friction between A and B. Length of A is 4 m and length of B is very small (g = 10 m/s2)
The time when B falls *** A. Initially B is on the right end of A. Ignore the dimension of B is :
(A) 1 *
(B) 3 *
(C) 2 *
(D) 4 *
