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
