a=r ω2 a=(25/100)(2 × 2 π)2 a=4 π2 m / s 2

Q. A particle moves in a circle of radius $25 c m$ at two revolutions per second. The acceleration of the particle is (in $m / s^{2}$ ),

$π^{2}$

$8 π^{2}$

$4 π^{2}$

$2 π^{2}$

$a = r ω^{2}$
$a = \frac{25}{100} (2 \times 2 π)^{2}$
$a = 4 π^{2} m / s^{2}$
