Question

In the arrangement shown in $Fig.6.355$, the block of mass $m=2kg$ lies on the wedge of mass $M=8kg$. The initial acceleration of the wedge, if the surfaces are smooth, is

• A. $\frac{\sqrt{3g}}{23}m{s}^{-2}$
• B. $\frac{3\sqrt{3g}}{23}m{s}^{-2}$
• C. $\frac{3g}{23}m{s}^{-2}$
• D. $\frac{g}{23}m{s}^{-2}$

Answer 1

The correct option is B $\frac{3\sqrt{3g}}{23}m{s}^{-2}$

Hence, option $\left(B\right)$ is correct answer.
