Three charges are at the corners of an equilateral triangle, as shown in the gure below. Calculate the electric eld at a point midway between the two charges on the x-axis. (Let q1 = 9.00 \"C, q2 = 7.50 MC, and q3 = 4.50 MC.) G) magnitude X Your response differs from the correct answer by more than 10%. Double check your calculations. N/C direction X Your response differs from the correct answer by more than 100%. below the +X-axis
