Question

A particle moves in a circle of radius 5cm with constant speed and time period 0.2πsec. The acceleration of the particle is?
1.
$15m {s}^{2}$
$2. \: 25m {s}^{2}$
$36m {s}^{2}$

$5m {s}^{2}$

​

Answer 1

2πr is the total path covered in O.2 πs
By dividing the distance travelled with time you can calculate the velocity
