pls solve this question correctly in 10 min i will give u like for sure

Physics28-Quiz#1 Be sure to explain your reasoning in your solution. Below we have 2 positive charges (charge +q) and 2 negative charges (charge -q) arranged in a square of side-length "a". a q a -q A) Find an expression for the electric potential at the point halfway between the two negative charges (in other words, at the bottom center edge of the square). please simplify your answer. You will need to use the pythagorean theorem. B) An electron starts from rest at the point described in part A). (Halfway between the two negative charges). It then accelerates towards the center of the square. Find an expression for the kinetic energy of the electron when it reaches the exact center of the square. (No need to simplify, no need to plug in numbers; use the usual constant "e" for the magnitude of the electron's charge, and me for the electron's mass.) Don't forget that the electron has a negative charge! (Hint: save yourself time and effort by referring to your answer from part A.)
