Three equally-spaced charges of equal magnitude are arranged in a line, as shown. The charge on the right is negative; the other two charges are positive.
If the charges each have a magnitude of 5.0 x 10-6 C, and there is a distance of 0.200 m between neighboring charges, what is the electric field at the point exactly halfway between the two positive charges?
Next problem : C - Potential from three charges.
Previous problem : A - Net force on a charge.
