1.	A spherical object of mass m is released on a smooth inclined plane which is inclined at anangle theta with the horizontal. State whether it will roll or slip. Give reasons in support of your answer.
Answer» Solution :No frictional FORCE acts on smooth plane. The only downward force ACTING on the centre on the centre MASS of the object along the INCLINED plane is m g sin`THETA` . But there is no torque about the centre of mass due to absence of the frictional force. So, the object will slip down without rolling with acceleration gsin `theta`.
