A cube of each side a is kept in an electric field given by E=cx (as shown in the figure) where c is a positive dimensional constant. Find out

(i) The electric flux through the cube and
(ii) The net charge inside the cube.

A charge q is placed at the centre of a cube. What is the electric flux passing through the cube?

A positive charge Q is situated at the centre of cube. The electric flux through any face of the cube is (in SI units)

A charge Q is situated inside a cube placed in air. The electric flux passing through all the six faces is-

A cube of length L is placed in a uniform electric field E. If two surfaces of the cube are perpendicular to E, then the total electric flux through the cube is—

A point charge +q is placed at the centre of a cube of side L. The electric flux emerging from the cube is

A charge q is placed at the centre of a cube of side l. What is the electric flux passing through each face of the cube?

Careful measurement of the electric field at the surface of a black box indicates that the net outward flux through the surface ofthe box is 8.0x10^3Nm^2//C . What is the net charge inside the box ?

A charge q is placed at the centre of a cube. What is the electric flux passing through two opposite faces of the cube ?

In vacuum (i) find out the electric flux across an area vec S = 10 hatj placed in an electric field vec E = 2 hati + 4 hatj + 7 hatk , (ii) How many electric charges are to be placed at a point such that 4400 number of electric lines of forces with emerge from that point ? (iii) What will be the electric flux through any one of the faces of a cube of side 10 cm if a charge of 1 esu is placed at the centre of the cube ?
