A solid plastic ball has a radius of 6.0 cm and has a charge of +3.o nC ( in nano-Coulombs) that is uniformly distributed throughout its volume. Imagine there is a proton being held 1.5 cm away from the surface of the solid plastic ball, and then the proton is released. The proton will accelerate away from the ball, as we know, due to the repulsive electric force. Assuming the ball doesn't move, how fast is the proton moving when it is 5.5 cm away from the surface of the ball?

Particle A is a neutral atom. When exposed to water, it oxidizes, and forms charged ions. The neutral atom loses 3 electrons when it underwent oxidation. State whether particle A is positively or negatively charged after oxidation. Calculate the overall charge on particle A after oxidation. After oxidation, particle A is placed at the origin on an x-axis. Particle B is an ion with and excess of 5 electrons compared to protons. Particle B is placed 5.7 x10-8 m to the right of the origin. Calculate the overall charge on particle B, and the magnitude of the potential energy between charges A and B. Particle C is a positive 4.98 x1019 C point charge. Particle C is placed 7.6 x108 m to the left of the origin.
