Question

a particle is revolving in a circle of redius 10 cm with linear speed of 20 m/s find its period of revolution and its frequency​

Answer 1

Answer:

s=d/t

# t=d/s

=0.1/20

=.005. revolutions

Answer 2

Explanation:

r=0.1 m

v=20m/s

T=2pir/v

=2×3.14×0.1/20

=0.0314s

f=1/T

=1/0.0314

=31.8 Hz
