a metal ring of mass m and radius R is placed on a smooth horizontal table and is set rotating about its own axis in such a way that each point of the ring moves with a speed v.find tension in the string .what i didn't understand is that they took the centripetal acceleration along the horizontal CO.why not along any other radial direction.and
a table with a smooth horizontal surface is turning at an angular speed W about its axis.a groove is made on the surface along a radius and a particle is gently placed inside at a distance a from the centre.find the speed when it is at a distance L from the centre.how to work it out from an inertial frame. rates assured!
