The figure shows a system consisting of three charges,q1 = +5.00uC, q2 = +5.00uC and q3 = -5.00uC, at the vertices of an equilateral triangle of side d = 2.55 cm.
A. Is the magnitude of the electric field halfway between the charges q2 and q3 greater than, less than, or the same as the electric field found in part A?
B. Find the magnitude of the electric field at the point specified in part B.
