A particle of mass m is attached with a string and it is rotated in a vertical circle, the tension at lowest point of the string will:
A particle of mass m is attached to M via a massless string passing through a hole O in the horizontal table as shown, Mass M is kept stationary whereas mass m is rotating in a circle of radius r with angular speed ω.
A body of mass m is moving in a circle of radius r with a constant speed v. The force on the body is mv2rand is directed towards the centre. What is the work done by this force in moving the body over half the circumference of the circle
