Question

A particle moves with constant speed v along a circular path of radius r and completes the circle in time T. The acceleration of the particle is

• A. $\frac{2\pi v}{T}$
• B. $\frac{2\pi r}{T}$
• C. $\frac{2\pi r^2}{T}$
• D. $\frac{2\pi v^2}{T}$

Answer 1

The correct option is A

$\frac{2\pi v}{T}$

Acceleration =${\omega }^{2}r=\frac{v^2}{4}=\omega v=\frac{2\pi }{T}v$
