A large positively charged object with charge q4 = 3.25 µC is brought near a negatively charged plastic ball suspended from a string of negligible mass. The suspended ball has a charge of q_ = -54.3 nC and a mass of 16.5 g. What is the angle the string makes with the vertical when the positively charged object is 21.5 cm from the suspended ball? The positively charged object is at the same height as the suspended ball.
