Question

Find acceleration of wedge so M' & M1 stay at rest relative to wedge​

Answer 1

Answer:

a=g tan @

Explanation:

taking the wedge as the frame of reference,

as the wedge is non-inertial frame,we add a pseudo force to both the blocks opposite to the direction of wedge acceleration...

as it is given that w.r.t wedge both blocks are at rest so,

from f.b.d of block M':

M'a cos @=M'g sin @

a =g tan @
