Question

A circular disc of radius R rolls without slipping along the horizontal surface with constant velocity v₀. We consider a point A on the surface of the disc. Then, the acceleration of the point A is 

(a) constant in magnitude 

(b) constant in direction 

(c) constant in magnitude as well as direction 

(d) None of the above

Answer 1

Correct option (c) constant in magnitude as well as direction  

Explanation:

The acceleration of the point A is will be constant in magnitude as well as direction
