A $300*10^-9$ coulomb test charge is placed near a negatively charged metal sphere. The sphere exerts an electrostatic force magnitude $6*10^-5$ newton on the test charge. What is the magnitude and direction of the electric field strength at this location? A$.200*10^4*$ N $/$ c directed away from the sphere B$.200*10^4*$ N $/$ C directed toward the sphere $5*10^-5$ N$/$C directed away from the sphere $.5*10^-5*$ N $/$ C directed toward the sphere
