3 charges are arranged on a rectangle as shown above.
What is the electric field at P3?
Give the x and y components, the magnitude, and the direction.
Specify the electric field to three significant places
and the angle to the nearest integer.
Use the convention that right is 0 degrees, up is 90 degrees,
left is 180 degrees, and down is 270 degrees.
ANSWER = ( Ex = -8.47e+7 N/C, Ey = -8.47e+7 N/C, |E| = 1.20e+8 N/C, angle = 225 degrees )
