1. Three particles are positioned at the vertices of an isosceles triangle as shown in the figure below. Let a = √2b. Give your answers in terms of the parameters a, b, y, and k a. What is the electric potential at a point x, located halfway between 91 and 43? b. Now, imagine you want to bring a fourth charge q = -q from far away to the location xo. How much work would be required to do so? +29 a b +9 a -9
