A particle of mass m is rotated in a circular path of radius r under the influence of a force F=-k/(r^2) , where k is a constant. Find the total energy of the particle.

An object , starting from rest, rolled down a smooth path. The path is one fourth of the circumference of a circle of radius r . What is the velocity of the object at the lower end of the path ?

Define centripetal force.A particle of mass m is rotating around a circular path of radius r. Find the centripetal acceleration of the particle and the magnitude and direction of the centripetal force acting on it.

A mass of 60 g remains attached to the end of a thread of length 4 m. The mass is rotated uniformly in a horizontal circular path. The plane of this circular path is at a vertical distance of 3.2 m from the upper end of the thread. Determine the tension in the thread and the time period of revolution of the mass.
