A body slides down on a frictionless track which ends in a circular loop of diameter D. The minimum height h in terms of D so that the body may just complete the circular loop, is

A body is allowed to slide down a frictionless track from rest position at its top under gravity. The track ends in a circular loop of diameter D . Then, the minimum height of the inclined track (in terms of D ) so that it may complete successfully the loop is

A body is allowed to slide down a frictionless track from rest position at its top under gravity. The track ends in a circular loop of diameter D . Then, the minimum height of the inclined track (in terms of D ) so that it may complete successfully the loop is

A body is allowed to slide down a frictionless inclined track under gravity from a height of 10 cm . The track ends in a circular loop of diameter D. The body is just able to complete the circular track , then the diameter of the track will be

An inclined track ends in a circular loop of diameter .D.. From what height on the track a particle should be released so that it completes that loop in the vertical plane ?
