A particle of mass 'm' attached to an inextensible string is moving in a vertical circle of radius 'r'.The critical velocity at the highest point is 'V0' to complete the vertical circle.The tension in the string when it becomes horizontal is___________
Dear sindhuja
critical velocity at the highest point is 'V0'
force balance at highes point
mg=mV02/r
or V02 =rg
now for motion from horizontal to highes point
energy balance 1/2 mv2 =1/2 mV02 +mgr
v2 =3gr
force balance T=mv2/r
=3mg
