What is the approximate magnitude of the electric field at point \(c\) ?

A. \(100 \mathrm{~V} / \mathrm{m}\)

B. \(300 \mathrm{~V} / \mathrm{m}\)

C. \(800 \mathrm{~V} / \mathrm{m}\)

D. \(1500 \mathrm{~V} / \mathrm{m}\)

E. \(3000 \mathrm{~V} / \mathrm{m}\)

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.
