\(\mathrm{A}+10 \mathrm{nC}\) charge is moved from point \(\mathrm{c}\) to point \(\mathrm{a}\). How much work is required in order to do this?

A. \(3.5 \times 10^{-6} \mathrm{~J}\)

B. \(4.0 \times 10^{-6} \mathrm{~J}\)

C. \(3.5 \times 10^{-3} \mathrm{~J}\)

D. \(4.0 \times 10^{-3} \mathrm{~J}\)

Refer to Figure Q21.24, which shows equipotential lines in a region of space. The equipotential lines are spaced by the same difference in potential, and several of the potentials are given.
