Electric Charges And Fields

Question

Wired Faculty App

If the radius of the Gaussian surface enclosing a charge is halved, how does the electric flux through the Gaussian surface change?

Solution

According to Gauss's law, Electric flux Φ_E is given by

ϕ_{E} = \oint \vec{E} . \vec{ds} = \frac{Q}{ε_{0}}

where Q is total charge enclosed in the closed surface.
On changing the radius of sphere, the electric flux through the Gaussian surface remains same as the net charge enclosed within the surface is same.

a) An electrostatic field line is a continuous curve. That is, a field line cannot have sudden breaks. Why not?
b) Explain why two field lines never cross each other at any point?
