Q. 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) $2\pi v/T$
B) $2\pi r/T$
C) $2\pi r^{2}/T$
D) $2\pi v^{2}/T$
Explanation
(a) Acceleration = $\omega^{2}r = \frac{v^{2}}{r} = \ \omega v = \frac{2\pi}{T}v$
