ELECTRIC FLUX
φ = ∫ E ⋅ dS
φ = ∫ E dS cosθ
Electric flux is the rate of flow of the electric field
through a given area & is proportional to the number of
electric field lines going through a virtual surface.
Maha Revision : Physics: Electrostatics and Current electricity
GAUSS’S LAW
Gauss’s theorem states that
the total electric flux through
a closed surface is equal to
1/ε0 times the total charge

φ = ∮ E ⋅ dS =
q/ε0
The surface over which we calculate the flux is called
Gaussian surface.

JEE Main 2023
Given below are two statements: One is labeled as Assertion A and the other
is labeled as Reason R.
Assertion A: Two metallic spheres are charged to the same potential. One of
them is hollow and another is solid, and both have the same radii. Solid
sphere will have lower charge than the hollow one.
Reason R : Capacitance of metallic spheres depend on the radii of spheres
In light of the above statements, choose the correct answer from the options
given below.
A
Both A and R. are true but R is not the correct
explanation of A
B
Both A and R. are true and R is the correct
explanation of A
C
A is false but R. is true
D
