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 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
