A small block of mass $m$ is lying at rest at point $P$ of a wedge having a smooth semi circular track of radius $R$ . The minimum value of horizontal acceleration $a_{0} ($ in $m / s^{2})$ of wedge so that mass can just reach the point Q , is

Answer:

Solution:

In the wedge frame, the pseudo force $m a_{0}$ does work $m a_{0} R$ over the horizontal displacement R.

To just reach Q, this must supply the potential rise $m g R$ .

$a_{0} = g = 10 m / s^{2}$

Answer: 10
