A wedge of mass m 1 and with angle rests on a horizontal surface. A block of mass m 2 is placed on the wedge. Assuming the friction to be negliible, find the acceleration of the wedge. Also find the acceleration of the block relative to the wedge.

```							FBD of block,We would get,N = m2gcos(alpha) {normal to wedge}andF = mgsin(alpha) {along the wedge}Hence along the wedge, accln. would be for the block. Hence,a2 = gsinalpha and the wedge would move rightwards only due to the Normal reaction from block in x direction component only.Hence,Nsin(alpha) = m1a1put N value we get,m2gcos(alpha)sin(alpha) = m1a1Relative accln. block w.r.t wedge would be =>a2 – a1 = gsin(alpha)*(1 – cos(alpha)) m/s^2
