loss of potential energy = work done=qV

anonymous · Answer

so what would the answer be?

anonymous · Answer

Potential energy difference = charge moved * Potential difference

This is just a definition. No other explanation about why it is so.

Find pot energy diff between A and B. It is all given. You are also given charge moved. It is very straightforward when you know all this.
\Please do the calculations\
