Question

Number of electric field lines emerging from 1nC

Answer 1

Given ,

Charge (q) = 1 nC or 1 × 10^(-9) C

As we know that ,

Gauss theorem states that the total flux through a closed surface is 1/Eo times to the net charge enclosed by the surface

Mathematically ,

$\boxed{ \sf{Φ = \frac{q}{ E_{o} } }}$

Where ,

Eo = 8.85 × 10^(-12) N-m²/C²

Thus ,

Φ = 10^(-9)/8.85 × 10^(-12)

Φ = 1.129 × 10^(2)

∴ The number of electric field lines emerging from charge is 1.129 × 10^(2)
