Question

The magnitude of the centripetal force on a mass
'm' moving with angular speed w' in a circle of
radius 'r' is:
A) mr^2w
B) mw^2
C) mrw^2
D) mr^2w^2

Correct answer is C

Explanation:
Centripetal force = mv^2/r
V= rw
Put the value of v into above equation
Centripetal force = mr^2w^2/r
Cancel r and you will get mrw^2

Answer 1

Answer:

centripetal force=mv^2/r

cancel r and you will get mrw^2

that's absolutely correct!
