A small block of mass `m` is released from rest from position `A` inside a smooth hemispherical bowl of radius `R` as shown in figure. Choose the wrong option (s)

Options

A. acceleration to block is constant throughout
B. acceleration of block is `g` at `A`
C. acceleration of block is `3g` at `B`
D. acceleration of block is `2g` at `B`

Answer

A, C

Explanation

Acceleration of block is not constant throught. Acceleration of block at `B` is `V^(2)//R` where `V^(2)=2 gR`.
