PhysicsW.E.P.Vertical circular motionEasy2 minQB

PhysicsEasysingle choice

A particle of mass $m$ is released from height $h$ on a smooth curved surface which ends into a vertical loop of radius $r$ , as shown. If $h = 2 r$ , then

Options:

Answer:

Solution:

To reach the top of loop, particle must have a minimum speed of $v = \sqrt{5 g r}$ at the bottom of the loop.

but $v^{2} = 2 g h = 4 g r$ , so the block won't reach the highest point of the track.
