Question

The number of electric lines of force that radiate outwards from $8.85\mu C$ of charges in a vacuum is:

• A. ${10}^{-6}$
• B. ${10}^{-12}$
• C. ${10}^{12}$
• D. ${10}^6$

Answer 1

The correct option is D ${10}^6$

The number of electric lines of force = ?

$Q=8.85\times {10}^{-6}C$

$\varphi =\frac{q}{{ϵ}_0}=\frac{8.854\times {10}^{-6}}{8.854\times {10}^{-12}}$

No. of line $=\varphi ={10}^6$.
