The magnitude of the electric field due to a point charge decreases with increasing distance from that charge. (Coulomb's constant: k = 8.99 x 10⁹ Nm²/C²) The electric field is measured 0.50 meters to the right of a point charge of +5.00 x 10⁹ C, (where 1 nano Coulomb = 1 nC = 1 x10 °C) What is the magnitude of this measured electric field? O 1.80 x 102 N/C O 5.56 x 103 N/C O 8.99 x 10' N/C 1.80 x 1020 N/C O 8.99 x 1020 N/C
