Question

the magnitude of the electric field at point c is
view available hint(s)
greater than the magnitude of the electric field at point b.
less than the magnitude of the electric field at point b.
equal to the magnitude of the electric field at point b.
unknown because the value of the electric potential at point c is unknown.

Explanation:

The magnitude of the electric field is related to the density of electric - field lines. If the electric - field lines are closer together at a point, the electric - field magnitude is larger at that point. Assuming a typical situation where the electric - field line density is lower at point C compared to point B, the magnitude of the electric field at point C is less than that at point B.

Answer:

less than the magnitude of the electric field at point B.
