A. The electric field is null at the point C; located in the middle of the

segment AB.

What is electric field?

Electric field is the region of space where the influence of electric force is felt.

Electric field at the middle of AB

E = kq/r²

where;

  • r is the middle of AB = 0.5 m

E(+6μC) = (9 x 10⁹ x 6 x 10⁻⁶) / (0.5²)

E(+6μC) = +216,000

E(-6μC) = (9 x 10⁹ x 6 x 10⁻⁶) / (0.5²)

E(-6μC) = -216,000

Sum of the electric field at the middle of AB

E(net) = E(+6μC) + E(-6μC)

E(net) = 216,000 - 216,000 = 0

Thus, the electric field is null at the point C; located in the middle of the

segment AB.
