What is the strength of the electric field 0.020 m from a 12 µC charge? (Use k=)

5.4 × 106 N/C
2.7 × 108 N/C
5.4 × 1012 N/C
2.7 × 1014 N/C

E = kq/r^2 = (9.0×10^9 N·m^2/C^2)(12×10^-6 C)/(0.020 m)^2
= (9.0×10^9)(12×10^-6)/(4.0×10^-4) ≈ 2.7×10^8 N/C.

(Direction: radially outward since the charge is positive.)
