ConceptDynamics of Uniform Circular Motion - Centripetal Force

Question

A particle of mass m is observed from an inertial frame of reference and is found to move in a circle of radius r with a uniform speed v. The centrifugal force on it is 

  • \[\frac{\text{mv}^2}{\text{r}}\] towards the centre

  • \[\frac{\text{mv}^2}{\text{r}}\] away from the centre  

  • \[\frac{\text{mv}^2}{\text{r}}\] along the tangent through the particle 

  •  zero

Solution

zero

The centrifugal force is a pseudo force and can only be observed from the frame of reference, which is non-inertial w.r.t. the particle.

 
  Is there an error in this question or solution?
