A neutral copper block is polarized as shown in the figure below, due to an electric field made by external charges (notshown).
Which arrow (a–j) in the figure below best indicates the direction of the net electric field at location B, which isinside the copper block?
1 answer:
Answer:
As point B is located inside the copper block so net electric field at point B is j.
Explanation:
Consider the figure attached below. The net electric field at location B,that is inside the copper block is zero because when a conductor is charged or placed in an electric field of external charges, net charge lies on the surface of conductor and there is no electric field inside the conductor. As point B is located inside the copper block so net electric field at point B is zero as well direction of net electric field at point B is zero.

Part a)
Part b)
Explanation:
Part a)
As we know that both charge particles will exert equal and opposite force on each other
so here the force on both the charges will be equal in magnitude
so we will have
here we have
now we have
Part b)
Now for the force between two charges we can say
now we have
now we have
