Q1 for Physics 2 Electrostatics

PROBLEM 1 1. (5 points). The gravitational and electrostatic forces are both conservative and inverse square laws but the difference between them is......................*.*; 2. (5 points). The electrostatic field inside a conductor in electrostatic equilibrium is 3. (5 points). At the surface of a conductor in electrostatic equilibrium, the electrostatic field is ....to the surface. 4. (5 points). What is the difference between charging an object by induction and charging by conduction? (be very specific or no credit will be given.) 5. (5 points). Suppose you are given a conductor that is completely isolated (no contact with its sur- roundings) and you make a cavity that goes deep inside this conductor, then you fill it (cavity) with positive charges. You then plug the hole with the same conducting material. After the electrostatic equilibrium is established, where will the charges go? BE BRIEF, DO NOT GO IN CIRCLES. The answer is short
