Question

Statement: "The electric field inside a block of aluminum (a conductor) must be zero." Let's assume you disagree with the statement. If the electric field was not zero inside the aluminum what would happen? Consider two charges, q_1 located at the origin and q_2 located a distance d to the right of the origin as shown below. If q_1 = q_2 in which region (i, ii, or iii) is the electric field zero? If q_1 and q_2 are equal in magnitude and opposite in sign in which region (i, ii, or iii) is the electric field zero? Charge q_1 = 2 mu C and q_2 = -4 mu C; in which region (i, ii, or iii) is the electric field zero? Charge q_1 = 2 mu C and q_2 = -4 mu C are separated by 10cm. What is the magnitude and direction of the electric field at x = 5cm? Identical point charges are fixed to the opposite corners of a square. Where does a third point charge experience the greater force, at one of the empty corners or at the center of the square? Explain your answer.

Explanation / Answer

Aluminum is a good conductor so electron moving all-over in the conductor in all direction but the net electric field is zero. if the electric field was not zero value then all the electrons flow along the field direction and there will net charge flow at every cross section. it means current will flow through the conductor without any electrical potential applied so it is not correct. so electric field must be zero....
