Question

The angular velocity of a body of mass = 1 kg in uniform circular motion is 20 rad/s. If the radius of the circle is 0.5m, find outward force experienced by it.
(a)40N
(b)400N
(c)200N
(d)20N​

Answer 1

(c)200N

Explanation:

Data:

mass=1kg

angular velocity w =20rad/s

radius=0.5 m

Required :

centrifugal force=?

solution:

as v=rw

v=(0.5)(20)

v= 10 m/s

Now centrifugal Force = mv2/r

=( 1)(10)2/0.5

=200N

Answer 2

Answer:

200N
