Transcribed Image Text:
Two identical balls of 3 g are suspended from threads of length 1.21 m and carry equal charges as shown in the figure. Each ball is 1.2 cm from the centerline. m X ChargeMag Losing Charge 0 | dq/dt= 9.89445 10-11 C S m q Now, assume the two balls are losing charge to the air very slowly. That means they'll be slowly approaching each other. If a ball is moving at an instantaneous speed of 2.2E 5 m/s, at what rate is the ball losing charge? Start by writing the speed of the ball and the rate of change of the charge as symbolic derivatives, and then relate those derivatives. Give your answer in Coulombs per second (C/s). Note that because the balls are losing charge so slowly, we can still use our results from the previous part, as the system is almost in equilibrium. Give your answer as a magnitude.

Answer rating: 100% (QA)
In this problem the balls are losing charge and therefore the electrostatic force between them decreases which causes them to approach each other Were asked to find the rate at which the ball is losin... View the full answer
