A sphere encloses an electric dipole with charge 3 10⁻⁶ C . What is the total electric flux across the sphere?
Options
- A-3 10⁻⁶ ~N - m ^2 / C
- Bzero
- C3 10^6 ~N - m ^2 / C
- D6 10⁻⁶ ~N - m ^2 / C
Correct answer
B. zero
Step-by-step solution
When a sphere encloses a charged dipole, Here, q= 3 10⁻⁶ C Thus, according to Gauss's law, the net electric flux across the closed surface is equal to the net charge enclosed by it divided by ₀ , i.e. _ E = q _ in ₀ = +3 10⁻⁶-3 10⁻⁶ ₀ =0 Hence, electric flux across the sphere is zero.
