A charge q1 = 5 nC is located at the origin of xy copedinate system, and a charge of q2 = -2 nC is located on the y-axis at y =.30m. Find the components of the electric field and its magnitude and direction at a point P with coordinates (.40m, .30m).

1 answer

For each:
Magnitude is E = kq/r^2
Direction do a tan-1.
The effect will be the vector sum of the two vectors (just sum the x and y coordinates of each)
