Question

The total electric flux, leaving spherical surface of radius 1cm and surrounding an electric dipole is

• A. $\frac{q}{\varepsilon_{0}}$
• B. Zero
• C. $\frac{2q}{\varepsilon_{0}}$
• D. $8\pi r^{2}.\frac{q}{\varepsilon_{0}}$

Answer 1

Answer: (B)

Zero

Answer 2

According to Gauss theorem, the total electric flux through any closed surface Φ = $\left( \frac{1}{\varepsilon_{0}} \right) \times$ [net charge enclosed by surface]

Further, the net charge due to a dipole is zero

∴ Φ = $\frac{1}{\varepsilon_{0}}$ x 0 = 0
