The bob of mass m,charge q is circulating in a verticle circle of radius r with the help of a string .If the max speed of the bob is v then the period of revolution is T1.If an electriv field of magnitude(mg/q)is setup which makes an angle 60 degree with upward verticle .again the bob is circulating in same circle and its max speed is also v then the period of rev is T2.Find T1/T2

Since this is a vertical circle,
radius of the circular motion (when angle made by the string with vertical is x) = l.sinx
Apply centripetal force by calculating the component of tension (T) = T.sinx
After electric field is set up, this force will act opposite to the direction of centripetal force, find the Tension now and calculate timeperiod from oscillation freqency.
