Question

A sphere encloses an electric dipole with charges 3 106 c. What is the total electric flux across the sphere? (1) 6 106 nm2/c (2) 3 106 nm2/c (3) zero (4) 3 106 nm2/c

Answer 1

Explanation:

3×10^_6

Because sphere enclose

Answer 2

The electric flux across the sphere is zero.

(3) is correct option.

Explanation:

Given that,

Charge $q=3\times10^{6}\ c$

We need to calculate the electric flux across the sphere

Using Gauss law

$\phi=\dfrac{q}{\epsilon_{0}}$

Where, q = net electric charge

Here, the net charge is zero because an electric dipole is a system of two charges +q and -q separated by a distance 2 d.

So, the flux through a closed surface containing an electric dipole will be zero.

Hence, The electric flux across the sphere is zero.
