Question

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 inclined track in terms of d so tht it may complete the loop successfully​

Answer 1

minimum is 2d please Mark brainliest

Answer 2

Answer:

(5d/4)

Explanation:

Velocity at bottom of loop to do complete circular motion is √5gr , where r is radius.

By applying conservation of energy :

mgh=(1/2)*m(5gd/2)

h=5d/4
