Question

A sphere s rolls without slipping moving with a constant speed on a plank p the friction between the upper surface of plank p and the sphere is sufficient to prevent sleeping while the lower surface of blank p is more than rests on the ground initially plant p is fixed to the ground by pin and if n is suddenly removed

Answer 1

1. Question⇒ A sphere s rolls without slipping moving with a constant speed on a plank p the friction between the upper surface of plank p and the sphere is sufficient to prevent sleeping while the lower surface of blank p is more than rests on the ground initially plant p is fixed to the ground by pin and if n is suddenly removed.

Explanation:

• In the absence of other forces, friction will not act when the body is having a pure rolling motion.
• (there will be no charge in the motion of S and P will still be at rest .
