Detailed Solution

Since there is no external force, the centre of mass of the system will be same.

$Let x_{1} is the wedge position from origin$

$x is the distance moved by wedge$

Let centre of mass of the wedge is at x₁ .

$\Rightarrow \frac{{Mx}_{1} + m (x_{1} + Lcosθ)}{(m + M)} = \frac{M (x_{1} + x) + m (x_{1} + x)}{(m + M)}$

$∴ x = \frac{mLcosθ}{(m + m)}$
