Question

A particle revolves round a circular path. The acceleration of the particle is inversely proportional to

• A. mass of particle
• B. radius
• C. velocity
• D. both (a) and (b)

Answer 1

Answer: (B)

radius

Answer 2

The centripetal acceleration $(a)=\frac{m v^{2}}{r} \propto \frac{1}{r}$. Therefore acceleration of the particle is inverely proportional to radius.
