Two points having charges `q_(1) and q_(2)` are placed at the coordinates (a, 0, 0) and (0, b, 0) respectively. Find out the electric field intensity of a third point charge placed at (0, 0, c) due to those two charges.

Answer

`(1)/(4pi epsilon_(0))[(q_(1)(-qhati+chatk))/((a^(2)+c^(2))^(3//2))+(q_(2)(-bhatj+chatk))/((b^(2)+c^(2))^(3//2))]`
