Three metallic isolated plates are given charges as shown in figure, the sum of the charges on the outer surfaces of the two plates (`1`) and (`3`) is (where `-3Q` and `4Q` are total charges of plates (`1`) and (`3`) respectively.)

Three very large plate are given charges as shown in the figure, if the cross -sectional area of each plate is the same the final charge distribution on plate C is

The ratio of charge on left surface of plate A to the charge on the right surface of plate B is +Q +3Q -20 (A) (B) (C)

Three identical plates of area A are arranged as shown. A charge +Q is given to plate ( 2 ). Then,

Force between two conducting large plates , with charges Q and Q/2 as shown in the figure, is (Area of each face of plate =A)

Force between two conducting large plates , with charges Q and Q/2 as shown in the figure, is (Area of each face of plate =A)

Figure shows three metallic plates with charges Q, 4Q, and -Q, respectively. Determine the final charges on all the surfaces.

Figure shows three metallic plates with charges Q, 4Q, and -Q, respectively. Determine the final charges on all the surfaces.

Three metallic plates out of which the middle is given charge Q as shown in the figure. The outer plates can be earthed with the help of switches S_1 and S_2 . The area of each plates is the same. Answer the following question based on the given passage. ,brgt The charge appearing on the outer surface of extreme left plate is

Four large identical metallic plates are placed as shown in the Figure. Plate 2 is given a charge Q. All other plates are neutral. Now plates 1 and 4 are earthed. Area of each plate is A. (a) Find charge appearing on right side of plate 3. (b) Find potential difference between plates 1 and 2.
