Two blocks A and B of equal masses mkg each are connected by a light thread, which passes over a massless pulley as shown. Both the blocks lie on wedge of mass mkg. Assume friction to be absent everywhere and both the blocks to be always in contact with the wedge. The wedge lying over smooth horizontal surface is pulled towards right with constant acceleration a (m/s2).
(g is acceleration due to gravity).
Normal reaction (in N) acting on block A.
(A) m/5(3g + 4a)
(B) m/5(3g - 4a)
(c) m/5(4g + 3a)
(D) m/3(4g - 3a)
