A 3.00 × 10^−9-coulomb test charge is placed near a negatively charged metal sphere. The sphere exerts an electrostatic force of magnitude 6.00 × 10^−5 newton on the test charge. What is the magnitude and direction of the electric field strength at this location? (1) 2.00 × 10^4 N/C directed away from the sphere (2) 2.00 × 10^4 N/C directed toward the sphere (3) 5.00 × 10^−5 N/C directed away from the sphere (4) 5.00 × 10^−5 N/C directed toward the sphere

(2) 2.00 × 10^4 N/C directed toward the sphere As the charge is positively charged and the metal sphere negatively charged, the force is attractive. The electric field strength is given by force/charge = 6.00 × 10^−5 newton/3.00 x 10^-9 C = 2.00 x 10^4 N/C
