(6) Two negatively charged spheres are interacting with each other. The sphere on the left has charge 91. = ~316nC' and mass mL = 5.769 and is attached to a rcpe which makes an angle 6 with the vertical. The sphere on the right has qR = 958nC' and is attached to a horizontal spring and is resting on a surface. The spring constant is k and is compressed A3 = 3.37am. This setup is shown below, and the charges are at the same elevation and separated by a distance d = 53.8mm. (a) What is the force of the left charge on the right charge? [4pts] (b) What is the spring constant, k? [4pts] (c) What is the tension in the rope? [3pts] (d) What is the angle 6 that the rope makes with the vertical? [3pts] (e) What is the total energy stored in the system consisting of the two charges and the spring? [pts] L
