List of top Physics Questions on Circular motion asked in Assam CEE

A particle of mass \(0.2\) kg is moving in a horizontal circle of radius \(r\) under a centripetal force equal to \[ -\frac{K}{r^5}, \] where \(K\) is a constant. What is the total energy of the particle?

A particle moves in a circle of radius \(R\) with a constant speed \(v\). The magnitude of the change in velocity after the particle has traveled half of the circular path is:
