Step 1
This means that the pseudo force acting on the block is equal to the centripetal force required to keep the block in circular motion. Show more…

A small block of mass $m$ lying at rest at point $P$ of a wedge having a smooth semi-circular track of radius $R$. What should be the minimum value of horizontal acceleration $a_{0}$ of wedge so that mass can just reach the point $Q$ ? (A) $g / 2$ (B) $\sqrt{g}$ (C) $g$ (D) Not possible
A small block with mass m slides without friction on the inside of a vertical circular track that has radius R. What minimum speed must the block have at the bottom of its path if it is not to fall off the track at the top of its path? Express your answer in terms of some or all of the variables m, R, and acceleration due to gravity g.
