Solved: Two point charges of the same magnitude but
Chapter 18, Problem 19.75(choose chapter or problem)
Two point charges of the same magnitude but opposite signs are fixed to either end of the base of an isosceles triangle, as the drawing shows. The electric field at the midpoint M between the charges has a magnitude EM. The field directly above the midpoint at point P has a magnitude EP. The ratio of these two field magnitudes is EM/EP 9.0. Find the angle in the drawing.
