Work done by a centripetal force A increases by decreasing the radius of the circle      B decreases by increasing the radius of the circle  C increases by increasing the mass of the body      D is always zero

Work done by a centripetal force A increases by decreasing the radius of the circle      B decreases by increasing the radius of the circle  C increases by increasing the mass of the body      D is always zero

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

When the force applied and the displacement of the body are inclined at 90º with each other, then work done isA infinite B maximum C unity D zero

What is the work done by a force in moving an object in a circular trajectory?2 marksZero Depends on the mass of the object Double the force Half the force

Describe the investigation you will conduct to find the relationship between the centripetal force and radius.
