i)in which situation the potential energy of the system the greatest?

ii)at what point (among A and B) the electric potential the greatest?

plzzzzzzzzzzz........ explain...........

Dear student,

Potential energy is given as

1/4pie. e(q1q2/r^2)

when charge is doubled, PE will also be doubled...
