MCQ
forceA 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
  • $2\,\pi \,v/T$
  • B
    $2\,\pi \,r/T$
  • C
    $2\,\pi \,{r^2}/T$
  • D
    $2\,\pi \,{v^2}/T$

Answer

Correct option: A.
$2\,\pi \,v/T$
a
(a)Acceleration$ = {\omega ^2}r = \frac{{{v^2}}}{r} = \omega v = \frac{{2\pi }}{T}v$
