Question

A solid cylinder is rolling down a rough inclined plane of inclination $\theta$. Then:

• A. The friction force is dissipative
• B. The friction force is necessarily changing
• C. The friction force will aid rotation but hinder translation
• D. The friction force is reduced if $\theta$ is reduced

Answer 1

The correct option is D The friction force is reduced if $\theta$ is reduced

If $\theta$ is reduced.

$mg\sin \theta$ is reduced

So, $f$ is reducedd
