Charge q1 = -6.5 nC is located at the coordinate system origin, while charge q2 = -1.5 nC is located at (a, 0), where a = 1.2 m. The point P has coordinates (a, b), where b = 2.1 m.

Question

(a) At the point P, find the x-component of the electric �field Ex in units of N/C.
(b) At the point P, find the y-component of the electric �field Ey in units of N/C.

Answer 1

a) Ex = -(1.5*10^-9*6.5*10^-9)/(1.2^2) = -2.8125*10^-17 N/C
b) Ey = -(1.5*10^-9*6.5*10^-9)/(2.1^2) = -1.7143*10^-17 N/C
