A wheel of radius 
rolls forward half a revolution on a horizontal ground. The magnitude of the displacement of the point of wheel initially in contact with the ground is
The correct answer is:
Horizontal distance covered by the wheel in half revolution 
So the displacement of the point which was initially in contact with ground
