# Question: a 194 109 c charge has coordinates x 0...

###### Question details

A 1.94 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 -5.40 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).
