1. Electric Charges and Fields
medium
The figure shows a hollow hemisphere of radius $R$ in which two charges $3q$ and $5q$ are placed symmetrically about the centre $O$ on the planar surface. The electric flux over the curved surface is
A
$\frac{{15}}{2}\frac{q}{{{\varepsilon _0}}}$
B
$\frac{{4q}}{{{\varepsilon _0}}}$
C
$\frac{q}{{{\varepsilon _0}}}$
D
$\frac{{2q}}{{{\varepsilon _0}}}$
Solution
$\frac{1}{2}\left[\frac{\mathrm{q}_{\mathrm{en}}}{\varepsilon_{0}}\right]=\phi$
$\phi=\frac{4 q}{\varepsilon_{0}}$
