1)The difference of potential between terminals of a battery is 6V. How much work is done when a series of negative charges totaling 0.5 C are moved from one terminal to another?

2) Two parallel metal plates have opposite charges and a difference of potential of 1000V between them. a) How mcuh work in eV (electrovolts) is done in moving an electron from the negatively charged plate to the positively charged plate? b) What is this work in joules?

Please explain. Thanks :)
