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
