Homework Statement
The work required to bring a negatively charged body from very far to either of the points indicated in the figure is greatest for point _____.
a. point A
b. point B
c. point C
d. point D
e. point E
Homework Equations
U = q_0*V or W (a-b) = (q*q_0)/(4*pi*epsilon_0)*[(1/r_a) -(1/r_b)]
The Attempt at a Solution
The negatively charged particle is moving against the electric field. As indicated by the equipotential lines, the electric field is strongest near the positive charge, so the potential V is greatest near the positive charge. If V is greatest at E, then won't the work at this point be greatest? (Or did I reverse it since a negative charge is involved and q*q_0 is negative?)
Thanks.
