Question

If the coefficient of friction between block & wedge is u, then the maximum horizontal acceleration of the wedge for which
block will remain at rest w.r.t. the wedge is -​

Answer 1

Answer:

B experiences a pseudo acceleration towards the left in A's frame, call this 'a'

Thus, for B to remain at rest,

μ(gcos45+asin45)=acos45−gsin45

because normal reaction on B is m(gcos45+asin45)

g(μ+1)=a(1−μ)

a=

(1−μ)

g(μ+1)
