The figure shows the electric field lines of three charges with charge $+1, +1$, and $-1$. The Gaussian surface in the figure is a sphere containing two of the charges. The total electric flux through the spherical Gaussian surface is
Positive
Negative
Zero
Impossible to determine without more information
How does the no. of electric field lines passing through unit area depend on distance ?
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
The wrong statement about electric lines of force is
In figure $+Q$ charge is located at one of the edge of the cube, then electric flux through cube due to $+Q$ charge is
Shown below is a distribution of charges. The flux of electric field due to these charges through the surface $S$ is
