Question
Charges at three corners of a square are shown in Figure P26.34, in which n = 9. To answer the following questions, use the letters k, Q, q, L, and m.

a) Write the electric field at point P in component form.
b)A particle with positive charge q and mass m is placed at point P and released. What is the initial magnitude of its acceleration?
Attempt at a Solution
Well, I was a little upset about this problem because I wonder if I'm getting the typing syntax correct. Anyways, here's what I came up with for an answer for the x coordinate of a(which is wrong):
-k(Q/(L^2))+kcos(45)((9Q)/(2L^2)^(1/2))
k is of course Coulomb's constant and Q is the charge, with L as the distance
Any ideas on what I am doing wrong here?
