a) calculate the electric field at a point A(5,4) m, in both magnitude and direction due to two electric charges q1 = 2.0 x 10^-9 C and q2 = -6.0 x 10^-9 C located at (0,4) m and (3,4) m respectively in the xy plane.(adsbygoogle = window.adsbygoogle || []).push({});

b) find the same components at the origin due to the same charges.

----------------------------------------------------------------

anyone want to point me in the right direction?

or let me know of a website where I can learn about these problems.. I know how to deal with 1 charge.. but have no idea with this question.

thanks for any help.
