3. The irregularly shaped conductor shown below has three inner cavities. Initially it has a charge of -5 C placed on it. Then point charges of 2 C, -1 C, and -3 C are introduced into the cavities as shown. Once things have settled into equilibrium, find the charges residing on each of the conductor's four surfaces. * 20 net charge on conductor --5 C

Before starting the experiment on Coulomb's law experiment you had a lesson on electrostatic phenomena. You learned that in a static situation, if there is excess charge on a conductor, 1. it keeps leaking from the surface to surrounding atmosphere until the whole amount of excess charge is gone 2. it remains concentrated at the center part 3. it spreads over the surface of the conductor 4. it's under a constant motion throughout the conductor surface
