PhysicsW.E.P.Vertical circular motionEasy2 minPYQ_2020

PhysicsEasysingle choice

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

Options:

Answer:

Solution:

For looping the loop $v = \sqrt{5 gr}$

By law of conservation of energy

Loss in potential energy = Gain in kinetic energy

$\Rightarrow mgh = \frac{1}{2} {mv}^{2} \Rightarrow h = \frac{5 r}{2}$
