An empty parallel plate capacitor is connected between the terminals of a 18.8-V battery and charges up. The capacitor is then disconnected from the battery, and the spacing between the capacitor plates is doubled. As a result of this change, what is the new voltage between the plates of the capacitor

Explanation:

From the question we are told that:

Potential difference

New Capacitor

Generally the equation for Capacitor capacitance is mathematically given by

Generally the equation for New p.d' is mathematically given by

i don't know that i agree with that but what's the question ?

overcharge is the right answer system
