Question asks: A point charge q = 4.9 μC is placed at each corner of an equilateral triangle with sides 0.25 m in length. What is the magnitude of the electric field at the midpoint of any of the three sides of the triangle?

If you can solve for any midpoint in the triangle and you are given the distance between each point, why do you have to solve for the height of the triangle in order for the problem to be right?
