Step 1

Part a

Given:

Two metal objects are placed having net charge +99 pC and -99 pC resulting in potential difference = 16V.

We need to find the capacitance.

Step 2

Capacitance of a system is the ratio of change in charge to the change in potential difference corresponding to it.

Capacitance, charge and potential difference are related as:

Step 3

Part b

Given: Charge is changed to +230 pC and -230 pC. We have to find the change in the capacitance.

The capacitance does not depend on charge or voltage. It depends upon the structur...
