Charge q2 in FIGURE P22.49 is in equilibrium. What is q1?
1 Charge & Coulomb's Law Charge Is a property of matter. There are two kinds of charge, positive “+” and negative “−”.1 1. An object can have positive charge, negative charge, or no charge at all. A particle which has charge causes a force-per-charge-of-would-be-victim vector to exist at each point in the region of space around itself. The infinite set of force-per-charge-of-would-be-victim vectors is called a vector field. Any charged particle that finds itself in the region of space where the force- percharge-of-would-be-victim vector field exists will have a force exerted upon it by the force-percharge-of-would-be-victim field. The force-per-charge- of-would-be-victim field is called the electric field. The charged particle causi
