A block of mass m is placed on a wedge of mass M. Coefficient between then is `mu lt cot theta `. The wedge is given an acceleration to its left. Find the maximum acceleration at which block apears stationary relative to wedge.

(a) `(g( sin theta - mu cos theta ))/( cos theta + mu sin theta)`

(b)`(g( sin theta + mu cos theta ))/( cos theta - mu sin theta)`

(c)`( g ( cos theta + mu sin theta ))/( cos theta - mu cos theta ) `

(d)`( g ( cos theta - mu sin theta ))/( cos theta + mu cos theta ) `
