Two point charges q_1 = 2.10 nC and q_2 = -6.20 nC are 0.100 m apart. Point A is midway between them; point B is 0.080 m from q_1 and 0.060 m from q_2 (the figure (Figure 1) ). Take the electric potential to be zero at infinity.

    Ah yes, I forgot to include that. The questions are: 1. Find the potential at point A. 2. Find the potential at point B. 3. Find the work done by the electric field on a charge of 2.10 nC that travels from point B to point A.

    kq/r is V for a: 9E9*(2.1E-9)/.05 + 9E9(-6.2E-9)/.05

    do the same for point b Work = delta E = q*delta V = q(V(B)-V(A))

    V isn't a vector
