A bar of uniform density has a mass of 6.00 kg and has a point charge at one end and is pinned at the other. A second charge of 0.30 C is placed directly below the first point charge and the system reaches equilibrium as shown. The system is in equilibrium with only the force due to gravity, pin forces, and the electrostatic force acting on the system. The gravitational force is vertical, and the point charge has negligible mass. What is the charge on the initial point charge? b, L = 0.4 m 25°

Science fiction author Larry Niven hypothesized a device that could neutralize the electric charge on the electrons in a object. When this happened, the mutual repulsion between the protons would rip the object apart on an atomic level, but rather than being instantaneous, the process took several seconds to take full effect.Suppose that this device is used on a 20.0-g block of lead, which is held rigidly fixed in place. The device neutralizes the charge of 2.3% of the electrons. Before the lead block rips itself apart, it is put into contact with a 20.0-g lead bullet which is initially uncharged. The bullet immediately contributes enough electrons to the block that the charges on the block and bullet are equal, and then the force of electrostatic repulsion launches the bullet. What is the charge on the bullet just before it launches? Assume that lead has an an atomic mass of 207.2 g/mol, and there are 82 electrons in a lead atom. -9300 C 8800 C 9300 C -8800 C 5.48 x 1022 C
