Question

The electric flux through the curve surface of a cone. Due to a charge $Q$ placed at its mouth,

• A. $\varphi =0$
• B. $\varphi >\frac{Q}{2_{\epsilon 0}}$
• C. $\varphi >\frac{Q}{{\epsilon }_0}$
  
• D. $\varphi =\frac{Q}{2_{\epsilon 0}}$

Answer 1

The correct option is B $\varphi >\frac{Q}{2_{\epsilon 0}}$

The electric flux through the curve surface of a cone $\varphi =\frac{Q}{2{ϵ}_0}$

When $\varphi >\frac{Q}{2{ϵ}_0}$
