# P 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. - Physics

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?
