- A 1.82 10-9 C charge has coordinates x = 0, y = −2.00; a 2.88 10-9 C charge has coordinates x = 3.00, y = 0; and a -4.90 10-9 C charge has coordinates x = 3.00, y = 4.00, where all distances are in cm. Determine magnitude and direction for the electric field at the origin and the instantaneous acceleration of a proton placed at the origin.
(a) Determine the magnitude and direction for the electric field at the origin (measure the angle counterclockwise from the positive x-axis).
(b) Determine the magnitude and direction for the instantaneous acceleration of a proton placed at the origin (measure the angle counterclockwise from the positive x-axis).

My professor does not walk us through the problem. He literally just gave us an equation and that's it. I do not know how to do this problem.
