If the body is moving in a circle of radius r with a constant speed v , its angular velocity is

A body of mass m is moving in a circle of radius r with a constant speed v, The force on the body is (mv^(2))/(r ) and is directed towards the centre. What is the work done by the force in moving the body over half the circumference of the circle?

A body of mass m is moving in a circle of radius 'r' with a constant speed v. The force on the body is (mv^(2))/(r) and is r directed towards the center. If work done by this force in moving the body over half the circumference and complete circumference is W and W', then:

A particle is moving in a circle or radius r centred at O with constant speed v. The change in velocity in moving from P to Q (angle POQ=40^(@)) 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 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

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

A particle is moving in a circle of radius r centred at O with constant speed v . What is the change in velocity in moving from A "to" B (/_ AOB = 40^@) ?
