A small block of mass m rests on a smooth wedge of angle `theta`. With what horizontal accelaration a should the wedge be pulled, as shown in fig, so that the block falls freely?

`g cos theta`

`g sin theta`

`g cot theta`

`g tan theta`

Text Solution

Verified by Experts

The correct Answer is:

`tan theta=g/a implies a=g cot theta`
