Find the distance moved by wedge when the block just reaches ground in fig.

A

Mhcot⁡θM−m\frac { M h \cot \theta } { M - m }

B

Mhtan⁡θM+m\frac { M h \tan \theta } { M + m }

C

Mhtan⁡θM−m\frac { \mathrm { Mh } \tan \theta } { \mathrm { M } - \mathrm { m } }

D

Mhcot⁡θM+m\frac { M h \cot \theta } { M + m }

Answer

Mhcot⁡θM+m\frac { M h \cot \theta } { M + m }

Explanation

Solution

mh cot θ = -(M + m)x

x = - Mhcot⁡θM+m\frac { M h \cot \theta } { M + m }
