Question
Two neutral metal spheres are insulated from the tabletop they rest on. A positively charged rod is initially far from the spheres. Before each action below, the system is returned to this initial condition. The spheres are near each other but do not touch, and the rod is brought near sphere A, but does not touch. The rod is held at rest near sphere A. ls the net charge on sphere A positive, negative, or zero? ls the net charge on sphere B positive, negative, or zero? Explain the reason for your response: The spheres touch each other, and the rod is brought near sphere A, but does not touch. The rod is held at rest near sphere A. Is the net charge on sphere A positive, negative, or zero? ls the net charge on sphere B positive, negative, or zero? Explain the reason for your response: The spheres are near each other but do not touch, and the rod touches sphere A. The rod is then removed. Is the net charge on sphere A positive, negative, or zero? Is the net charge on sphere B positive, negative, or zero? Explain the reason for your response: The spheres touch each other, and the rod touches sphere A. The rod is then removed. Is the net charge on sphere A positive, negative, or zero? ls the net charge on sphere B positive, negative, or zero? Explain the reason for your response:Explanation / Answer
a) Net charge on sphere A is 0 because although the separation of charges takes place within the sphere but the charges cannot flow.
Net charge on sphere B is 0 because although the separation of charges takes place within the sphere but the charges cannot flow.
b)Net charge on sphere A is negative due to induction as excess electron flow into in from sphere B.
Net charge on sphere B is positive due to induction because excess electrons flow into sphere A.
c)Net charge on sphere A is positive as it is charged by conduction.
Net charge on sphere B is zero because although the separation of charges takes place within the sphere but the charges cannot flow..
d)Net charge on sphere A is positive as it is charged by conduction.
Net charge on sphere B is positive as it is charged by conduction.
