A block of mass m is placed on an inclined plane. With what acceleration A towards right should the system move on a horizontal surface so that m does not slide on the surface of inclined plane? Also calculate the force supplied by wedge on the block. Assume all surfaces are smooth.

Text Solution

Verified by Experts

For discussion of the block inclined plane is taken as reference frame.
From the force diagram
`N=mg cos 37^(@)+ma_(0)cos 53^(@)`
`=40 + 15 =55 N`.
