A charge of -10 microcoulumbs is located at the origin of an x-y coordinate system. Another charge of -10 microcoulumbs is located at the point (0, 2.0 m). Determine the electric field and the electric potential at the point (0, 1.0 m).
Here is what I did. Is this the correct way?
E1 = (9*10^9) (10*10^-6)/1^2 = 90,000 N/C
E2 = (9*10^9) (10*10^-6)/1^2 = 90,000 N/C
Etotal = 90,000 - 90,000 = 0 (Electric field)
V1 = (9*10^9) (-10*10^-6)/1^2 = -90,000 V
V2 = (9*10^9) (-10*10^-6)/1^2 = -90,000 V
Vtotal = -90,000 + -90,000 = -180,000 V (Electric potential)
