A wheel of radius 20 cm is pushed ot move it on a rough horizontal surface. It is found to move through a distance of 60 cm on the road during the time it completes one revolutionabout the centre. Assume that the linear and the angular accelerations are uniform. The frictional force acting on the wheel by the surface is

A

along the velocity of the wheel

B

opposite to the velocity o the wheel

C

perpendicular to the velocityof the wheel

D

zero
