Homework Statement
Point charges q and Q are positioned as shown. If q= +1.0 nC, Q = -2.0 nC, a = 3.0m, and b = 4.0m, what is the electric potential difference, Va - Vb? **The question with the diagram is also attached **
Homework Equations
V = ke (q/r)
The Attempt at a Solution
V = (8.99x10^9)[(1.0x10^-9)/4) = 2.2475 V.
The anser is 3.6V though, so I don't understand what I am doing wrong!
