###### Question details

Four charged particles are at the corners of a square of side a as
shown in the figure below. (Let A = 4, B = 5, and C = 3. Assume q
is positive.) (a) Determine the electric field at the location of
charge q. (Use the following as necessary: q, a, and ke.) magnitude
E = Incorrect: Your answer is incorrect. direction °
(counterclockwise from the +x axis) (b) Determine the total
electric force exerted on q. (Use the following as necessary: q, a,
and ke.) magnitude F = Incorrect: Your answer is incorrect.
direction ° (counterclockwise from the +x axis)
