A Block 'A' is placed on a smooth horizontal surface and particle C is suspended with the help of light rod from point B of the block as shown. Now both the block A and the particle C are given velocity `v_(0)` towards left. The block A strikes a fixed wall and suddenly stops. Then, (The rod BC is free to rotate about B)

The smallest velocity `v_(0)` for which the particle C will swing in a full circle about the point B is `sqrt(4gl)`

The smallest velocity `v_(0)` for which the particle C will swing in a full circle about the point B is `sqrt(gl)`

Velocity of point C at the highest point of the circle (for the smallest value of `v_(0)`) is zero

Velocity of point C at the highest point of the circle (for the smallest value of `v_(0)`) is `sqrt(gl)`
