Consider an equilateral triangle, inscribed in a circle of radius a, with a point charge q at each vertex. The electric field is zero at the center, but surprisingly there are three other points inside the triangle where the field is also zero. Where are they? Find the distance from these points to the center of the circle.
Please just get the answer to E in terms of a, x, and y. I only need you to solve up to the solution for E in terms of a, x, and y. Thank you!
