Name____________________________________ Coulomb’s Law 1) An very small spherical object with a – 6.0 nC charge is brought in contact with another very small sperical object with a +3.6 nC charge. a) What is the final charge on each object once they reach equilibrium. b) How many charges are transferred between the objects? 2) Determine the magnitude and direction of the force acting on the +5 μC charge in the diagram below. 3mm 4mm 5μC -3μC -7μC
