Question

A charge q is placed at one corner of a cube. the electric flux through any

Answer 1

Answer:

Explanation:

Here we have to find flux of the faces which are not touching this charge here Q. So there are three faces which are not touching this charge Q.

Hope this helps you.

Answer 2

Q). A charge q is placed at one corner of a cube. The electric flux through any of the three faces adjacent to the charge is 0. The flux through any one of the other faces is :

A. q/3∈0

B. q/6∈0

C. q/12∈0

D. q/24∈0

The correct answer is option D

Given.

Charge = q

Electic flux through any of the three faces adjacent to the charge  = 0

To Find.

The flux through any one of the other faces.

Solution.

Based on the given problem, the charge is placed at the corner of the cube as shown in figure 1.

Now consider another figure in which the whole charge is enclosed in four cubes.

so we can write as:

Фe = q/∈0 = EA

Where A=6∗(2a)²

For one side of the first cube,

Area  Ao = α²

From the above data,

Фe = Q/∈0 = Ea0.where Q =q/24

So flux through a single face is q/24∈0.
