Question

The centripetal force acting on a particle in UCM is proportional to?​

Answer 1

Answer:

It increases, because the centripetal force is directly proportional to the mass of the rotating body. It increases, because the centripetal force is inversely proportional to the mass of the rotating body. It decreases, because the centripetal force is directly proportional to the mass of the rotating body.

Answer 2

The centripetal force is directly proportional to the mass and velocity and it is inversely proportional to the radius of the circle.

Explanation:

The centripetal force acts on an object when it moves in a circular path. The magnitude of centripetal force is given by the formula as :

$F=\dfrac{mv^2}{r}$

Here,

m is the mass of the object

v is the speed of object

r is the radius of the circular path

So, it is clear that the centripetal force is directly proportional to the mass and velocity and it is inversely proportional to the radius of the circle.
