Questions
A sphere of radius R is executing pure rolling on a rough horizontal surface. The acceleration of the point of contact is
a
zero
b
v2R towards the centre
c
v2R away from the centre
d
v2R at an angle 450 with horizontal direction
detailed solution
Correct option is B
The point of contact stays at instantaneous rest when a rigid body is executing pure rolling i.e. the point of contact will not have any tangential acceleration. Hence it will have centripetal acceleration.Talk to our academic expert!
