A small sphere of mass m = 0.6 kg carrying a positive charge q = 80 microCoulomb is connected with a light, flexible and inextensible string of length r = 30 cm and whirled in a vertical circle. If a horizontal rightward electric field of strength E = 100000 N/C exists in the space, then the minimum velocity of sphere required at the highest point so that it may just complete the circle will be ( g = 10 m/s^2 )
a) Greater that 5m/s
b) approximately 3 m/s
c) less than 2 m/s
d) approximately 5 m/s
