Question 2 of 24 · 3.5 marks

Consider a charge $Q$ at the origin of 3 - dimensional coordinate system. The flux of the electric field through the curved surface of a cone that has a height $h$ and a circular base of radius $R$ (as shown in the figure) is

1. 1$\frac{Q}{{ϵ}_0}$
2. 2$\frac{Q}{2{\in }_0}$
3. 3$\frac{hQ}{R{ϵ}_0}$
4. 4$\frac{QR}{2h{ϵ}_0}$

Correct answer: Option 2
