Consider 3 charges arranged as shown. Y II -5.6 C III 1.9 C 0.95 m 1.9 m 0 I I -3.89 C IV Find the direction of the resultant electric force on the -3.89 C charge at the origin due to the other two charges. The value of the Coulomb constant is 8.9875 x 10" N-m/C. part 2 of 3 Determine the magnitude of the resultant electric force on the -3.89 C charge at the origin due to the other two charges. Answer in units of N. Answer in units of part 3 of 3 Determine the direction of the resultant electric field on the -3.89 C charge at the origin due to the other two charges.
