Question
A conducting metal block ABCD is placed in an electric field of strength E as shown in the figure below. Which of the following statements is correct about the charge inside the block? The side AB will have an excess positive charge and the side CD will have an excess of negative charge. The side CD will have an excess positive charge and the side AB will have an excess of negative charge. The side AD will have an excess positive charge and the side BC will have an excess of negative charge. The side BC will have an excess positive charge and the side AD will have an excess of negative charge. Since here was no excess charge placed on the block, none of the sides will have an excess charge. When a hollow conductor is placed in an external electric field E. the electric field inside the conductor is found to be E'. Compare E and E' Cannot answer without knowing the amount of charge in the conductor. How is the charge on the sphere distributed? Charge is concentrated at the center of the sphere. Charge is uniformly distributed in the volume of the sphere. Charge will be at the surface of the sphere. Entire charge will move to the inner surface of the outer shell. What is the net charge on the inner surface of the outer shell? What is the net charge on the outer surface of the outer shell?Explanation / Answer
(1)ans
CD is positive charge and AB is negative charge
basing on electric flux condition the charge is living at positive charges and enter at negative charges
so here in the side AB is the electric flux is entering so this is negative plate
in the side CD is the electric flux is leveing so this is positive plate
(2) ans
the hallow conductor is placed is in electric field the electric field in side the coductor is zero
E' = 0
because hallow conductor is closed body if any closed body is placed in electric field does not enclose any charge
(3) ans
charge is uniformly distributed in the volume of sphere
(4) ans
the net charge on the inner surface of the outer shell is Q
that means the the total charge is concentrated at the centre of sphere
(5) ans
the net charge on the outer surface of the outer shell is zero
that means the total charge enclosed is concentrated is zero so the charge is zero
