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
