let it fall when it makes an angle

two forces acting mgcos

and normal reaction R

at instant it falls N=0

so mgcos

=mv²/r

as mgcos

provides centripetal force

v²/r=gcos

conserving energy,so

mgr(1-cos

)=1/2mv²

subs, value of v²/r

we get cos

=2/3

hope u got it

rate me if satisfied

Anyone who has never made a mistake has never tried anything new
You can never solve a problem on the level on which it was created.
When you are courting a nice girl an hour seems like a second. When you sit on a red-hot cinder a second seems like an hour. That's relativity

Purpose of solving a problem is not simply to get the answer(the answer is only an evidence) but to develop your thinking ability
