A positive charge ball hangs, attached to a thread of negligiblemass. Similarly a negative charged ball hangs attached to athread of negligible mass. Each ball has mass of 0.14g and amagnitude charge of q. Attracted to each other, each of theirthread form a 20 degree angle from the vertical. The ballsare separated by a distance of 2.05 cm.
a) find the magnitude of the electric force acting on eachball; a)___________________
b) the tension in each thread, and b)___________________
c) the magnitude of the charge on the balls c)___________________
