Attempt 4 The pictures show a rod made of silicone, a swatch of leather, and an insulated ball of gold, all initially uncharged. The rod is dragged across the leather in order to transfer some charge. Label the signs of the electric charge on the silicone and the leather. Once the rod is charged, it is placed near the gold ball without making contact. Label the rod and the near and far sides of the gold ball with the signs of their electric charges. Answer Bank ++++ no charge Rod

Imagine a setup as below, where the Green object is attached to the ceiling with a rotatable rigid rod, and an Orange object is fixed to a wall and d .. m1 Q1 m2 Q2 The Orange object has a charge configuration of Q2 = -10 Coulombs. The Green object's charge configuration Q1 is unknown. The distance between the center of the Orange and Green objects is d=8 millimeters. The mass of the Orange object is m, (the value is irrelevant for this question) and the Green object has a mass of m, = 11 grams. The setup is in equilibrium, that is, the net force on the Green object is zero (hence, it has zero acceleration). If the angle is 0=6 degrees, what is the value of the Green object's charge Q, in Coulombs? IMPORTANT: The actual answer is in the form of 10 18. Write only the number before it.

Coulomb's Law A thin rod of length L, oriented in the x-direction, has charge +Q. The rod lies on the floor. The left end of the rod is touching a wall. On the floor, a small frictionless puck of mass M and charge Q is also touching the wall. The puck is a distance b from the left end of the rod. If the wall were removed, the puck would slide at an angle. But the wall constrains the puck to slide only in the y-direction. Here, the y-direction is not vertical. It's along the floor, perpendicular to the rod. a. What is the puck's acceleration, immediately after it's released? Hint: The wall constrains the puck to accelerate only in the y-direction. Therefore, you need to worry only about the y-directed forces. If you can't complete the math, that's OK; but set things up completely. Top down view Base of wall Puck b. What normal force does the wall exert on the puck when the puck is first released? Hint: The normal force, which points in the x-direction, must cancel the x-component of the…
