Two small particles A and B having masses m=0.5 kg each and charges q1=(−155/18μC) and q2=(+100μC), respectively, are connected at the ends of a nonconducting, flexible, and inextensible string of length r=0.5m. Particle A is fixed and B is whirled along a verticle circle with center at A. if a vertically ipward electric field of Strength E=1.1×105NC−1 exists in the space, calculate the minimum velocity of particle B required at the highest point so that it may just complete the circle (g=10 ms^−2).
