A figure shows two charges of -q arranged symmetrically about the y axis. Each produces an electric field at P. Assume the point P is 2 meters above the origin, and d= 1 meter, with the absolute value of the charge q=4.5 uC
a- Are the magnitudes of the electrical fields equal? why or why not?
b- in what direction does each electrical field point?
c- Is the magnitude of the electrical field equal 2 E if E is the magnitude of one of the fields?
d- Does the x components of the two electrical fields add or cancel?
e- Do the y components of the two electrical fields add or cancel?
f- Compute the net electric field and write it in unit vector notation.
