CE Predict/Explain Suppose the charged sphere in Active
Chapter 19, Problem 16P(choose chapter or problem)
Suppose the charged sphere in Active Example 19–2 is made from a conductor, rather than an insulator. (a) Do you expect the magnitude of the force between the point charge and the conducting sphere to be greater than, less than, or equal to the force between the point charge and an insulating sphere? (b) Choose the best explanation from among the following:
The conducting sphere will allow the charges to move, resulting in a greater force.The charge of the sphere is the same whether it is conducting or insulating, and therefore the force is the same.The charge on a conducting sphere will move as far away as possible from the point charge. This results in a reduced force.

QUESTION:
Suppose the charged sphere in Active Example 19–2 is made from a conductor, rather than an insulator. (a) Do you expect the magnitude of the force between the point charge and the conducting sphere to be greater than, less than, or equal to the force between the point charge and an insulating sphere? (b) Choose the best explanation from among the following:
The conducting sphere will allow the charges to move, resulting in a greater force.The charge of the sphere is the same whether it is conducting or insulating, and therefore the force is the same.The charge on a conducting sphere will move as far away as possible from the point charge. This results in a reduced force. ANSWER:
Step 1 of 4
(a)
In the given case, we need to comment whether the magnitude of force exerted by conducting sphere on a point charge will be greater, lesser or same as that of the magnitude of force exerted by the insulated sphere on the same point charge. In both the case, other parameters remains uncharged.
