Question

# This is the result of inertia but is mistaken for an outward, real force.

- Centripetal force
- Centrifugal force
- Gravity
- Inertial force

Hint:

### The centrifugal force is a fictitious force

## The correct answer is: Centrifugal force

### 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.
