Question

A particle moves in a circular path of radius 10cm with a constant speed of 10 cm/s. It's acceleration is
a) 100 cm/s^²
b) 10 cm/s^²
c) 1 cm/s^²
d) zero

Answer 1

Given that,

Radius of the circular path = 10cm.

Velocity of the particle = 10 cm/s

Acceleration of the particle = ?

We know that,

$a_{c} = \frac{ {v}^{2} }{r} \\ a_{c} = \frac{ {(10 \: cm/s)}^{2} }{10s} \\ a_{c} = \frac{100 \: cm/s}{10s} \\ a_{c} = 10 \: cm/ {s}^{2}$

Therefore, the acceleration is 10 cm/s^2.

Hope this helps you.
