A -18.3 nC charge is located at position (x,y) = (3.50 cm, 1.75 cm). At what (x,y) position is the electric field -209150.0i? (Enter your x position first followed by the y position.)
E = (1/4pi epsilon naught)(q/r^2)
Epsilon naught = 8.85x10^-12 C^2/N*m^2
The Attempt at a Solution
I substituted the charge and electric field position and solved for r = 3.1194x10^-12 m
What do I do form there?
