An inclined track ends in a circular loop of radius r. From what height on the track a particle should be released so that it completes the loop, assuming there is no friction ?

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

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 ?

For looping a loop of radius 4 m through what minimum height should a particle descend ?

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 block is released from rest at the top of an inclined plane which later curves into a circular track of radius r as shown in figure. Find the minimum height h from where it should be released so that it is able to complete the circle.
