Question

A small smooth ring of mass m is threaded on a light
inextensible string of length 8L which has its ends fixed
at points in the same vertical line at a distance 4L apart.
The ring describes horizontal circles at constant speed
with both parts of the string taut and with the lower portion of the string horizontal
portion of the string horizontal. Find the speed of the
ring and the tension in the string. The ring is then tied
at the midpoint of the string and made to perform
horizontal circles at constant speed of 3/gL . Find the
tension in each part of the string.
