Answer :
The centripetal force acting on the ball revolving 35 times per minute around a circle with a 25 cm radius is 1.68 N
What is centripetal acceleration?
The characteristic of an object's motion when it travels along a circular-path is known as centripetal acceleration. Centripetal acceleration is the term for any moving object whose acceleration vector is directed toward the center of the circle.
The following informations are given in the question,
mass of the ball, m = 2kg
radius of the ball, r = 25 cm
= 0.25 m
time, t = 60 seconds
No of revoutions completed by the ball = 35
We know, Velocity = (No of revolutions x 2 π r )/t
= 35 x 2 x π x 0.25/ 60
= 0.46 m/s
The acceleration is, a = v^2/r
= 0.46 x 0.46/0.25
=0.84 m/s^2
The required centripetal force = 2 x 0.84
= 1.68 N
Hence, the Centripetal force is 1.68 N
