Answer

See explanation.

Work Step by Step

The electric field inside the conducting sphere is always zero in an electrostatic situation. This answer holds no matter where the sphere is located, or how much excess charge it carries. The electric potential is the same everywhere inside the sphere. However, the value of this potential depends on where it is located – if it is closer to the positive plate, it will be at a higher potential than if it is located farther from it. In a similar way, if it were positively charged, it will be at a higher potential than if it were negatively charged.
