A body of mass m and radius r is rotated with angular velocity `omega` as shown in the figure & kept on a surface that has sufficient friction then the body will move

backwards first and then move forward

forward first and then move backward

will always move forward

none of these

Text Solution

Verified by Experts

The correct Answer is:

Friction force on sphere is in the forward direction, sphere will always move in forward direction.
