Homework Equations
potential = kq1q2 / r
The Attempt at a Solution
The answer is D. Which states "The electric potential in P is higher than Q" is correct. But my answer is B. By right hand rule, the current goes from Q to P. The formula of potential has a positive sign. So I think Q has a higher potential as work is needed to move the protons from P to Q. Why am I wrong?
