PHYS 3 Chapter Notes - Chapter 23.1-23.3: Electronvolt, Probability Distribution, Electric Potential Energy
Document Summary
Remember: gauss"s law says that the electric field outside such a distribution is the. For every electric field due to a static charge distribution, the force exerted by that field is conservative. Equation 23. 2: work done by a conservative force: Equation 23. 3: increases if the test charge moves in the direction opposite the electric force, decreases if moves in the same direction as. Equation 23. 9: electric potential energy of two point charges: is zero when and are infinnitely far apart and. If and have the same sign, the interaction is repulsive --> work is positive and is. If and have opposite signs, the interaction is attractive --> work is negative and is. Equation holds if is outside a spherically symmetric charge distribution with charge is from to the cent er of the distribution same as if all of its charge were concentrated at its center.
