Gauss law helps in

- determination of electric field due to symmetric charge distributions
determining electric potential due to symmetric charge distributions
The Correct Option is C
Solution and Explanation
Gauss' law helps in the determination of the electric field due to symmetric charge distribution.
The Gauss Theorem
Net flux through a closed surface is directly proportional to the net charge in the volume enclosed by the closed surface.
ϕ=E⋅dS=\(\frac{q_{net}}{ \epsilon_0}\)
Gauss's theorem relates the ‘flow’ of electric field lines (flux) to charges within the enclosed surface. Net electric flow is always zero if no charges are contained by a surface. The number of electric field lines entering the surface equals the number of field lines ejecting from it.

Concepts Used:
Electrostatic Potential and Capacitance
Electrostatic Potential
The potential of a point is defined as the work done per unit charge that results in bringing a charge from infinity to a certain point.
Some major things that we should know about electric potential:
- They are denoted by V and are a scalar quantity.
- It is measured in volts.
Capacitance
The ability of a capacitor of holding the energy in form of an electric charge is defined as capacitance. Similarly, we can also say that capacitance is the storing ability of capacitors, and the unit in which they are measured is “farads”.

The capacitor is in Series and in Parallel as defined below;
In Series
Both the Capacitors C1 and C2 can easily get connected in series. When the capacitors are connected in series then the total capacitance that is Ctotal is less than any one of the capacitor’s capacitance.
In Parallel
Both Capacitor C1 and C2 are connected in parallel. When the capacitors are connected parallelly then the total capacitance that is Ctotal is any one of the capacitor’s capacitance.
