A charge of 0.5 oC is located at (x, y) = (0.00, 0.10) m and a charge of -1.00oC is placed at (x, y) = (0.20, 0.20) m.
(a) What are the x- and y-components of the electric field at point P = (0.1, 0.3) m?
(b) What is the magnitude of the electric field at point P?
(c) What is the polar direction (angle) of the field at point P, in degrees?
