Two small plastic balls hang from threads (1m long) ofnegligiblemass. Each ball has a mass of 0.09g and equal charges.The ballsare repelled by each other .they are 18cm apart and thethreadsattached to the balls make an angle of 25 degree with thevertical. Determine:
i) the magnitude of the electric force acting oneachball. ii) the tension in each of the threads. iii) the magnitude of the charge q on the balls.
