Question

For pure rolling to occur,

• A. There should be no tangential force acting on the body at the point of contact
• B. There should be a tangential force acting on the body at the point of contact
• C. There should be no normal force acting on the body at the point of contact
• D. net torque should be zero

Answer 1

The correct option is B There should be a tangential force acting on the body at the point of contact

For a pure rolling to happen, friction is essential and this will act tangential to the surface
