If a particle moves in a circle of radius r with constant speed under centripetal force F, then the work done in completing full circle will be ,

A particle moves in a circle of radius R with a constant' speed under a centripetal force F. The work done in completing a full circle is :

If a particle covers half the circle of radius R with constant speed then

If a particle covers half the circle of radius R with constant speed, then

A particle is moving in a circle with a constant speed. Its moving is

A particle is moving in a circle of radius R with constant speed v, if radius is double then its centripetal force to keep the same speed should be

A body of mass m is moving in a circle of radius r with a constant speed v. The work done by the centripetal force in moving the body over half the circumference of the circle is

A body of mass m is movinng in a circlee off radius r with a constant speed v. the work done by the centripetal force in moving the body over half the circumference of the circle is
