A block of mass m is placed on hthe top of bigger wedge M. All the surfaces are frictionless. The system is released from rest. Find the distance moved by smaller block (w.r.t triangular wedge) when bigger wedge travles distance X on plane surface

Options

A. `(2(m+M)X)/(sqrt3m)`
B. `((m+M)X)/(sqrt3m)`
C. `((m+M)X)/m)`
D. `(mX)/(m+M)`
