Question

# Identify what is wrong in the diagram?

- Velocity
- Centripetal force
- Centrifugal force
- None

Hint:

### The centrifugal force is a fictitious force. This force is assumed by an observer moving along the body in a circular motion to act in the direction away from the centre of circular path.

## The correct answer is: Centrifugal force

### Centripetal force is the component of force acting on an object in curvilinear motion which is directed towards the axis of rotation or centre of curvature. Centrifugal force is a pseudo force in a circular motion which acts along the radius and is directed away from the centre of the circle.

The velocity at any point in a uniform circular motion is given by tangent to that point in the direction of motion .

So centrifugal force is wrongly shown
