Here, electric field lines appear to emerge from positive charge and enter in negative charge. So, if an electric dipole is placed inside the sphere then the flux coming out from electric field lines of positive charge will be equal to the flux going out from electric field lines of negative charge.
What is the electric flux due to dipole?
The electric flux of a dipole is equal to zero. See, for every closed Gaussian surface we chose, wich contain dhe dipole, however we chise the surface the number of the exit force lines is equal to the number of inward force lines. So the total flux is zero.
What is the net electric flux passing through a sphere enclosing an electric dipole?
Find the electric flux passing through the sphere. Net charge inside the sphere qin=0. Therefore, according to Gaus’s law net flux passing through the sphere is zero.
What is the net value of electric flux across a dipole?
The net flux becomes zero. Since net charge becomes zero due to the equal and opposite charge on the dipole, the flux becomes zero.
What is the electric flux passing through a Gaussian?
According to Gauss’s law, the flux of the electric field →E through any closed surface, also called a Gaussian surface, is equal to the net charge enclosed (qenc) divided by the permittivity of free space (ϵ0): ΦClosedSurface=qencϵ0.
Why is a dipole flux zero?
In surface S3, as per the Gauss Law, the net electric flux is zero as there is no charge enclosed in the surface. Also the other reason the book mentions for this that since the amount of flux entering is equal to the amount leaving, the net flux is zero.
In which orientation a dipole placed in a uniform electric field is in unstable equilibrium?
-The dipole is in unstable equilibrium when it is oriented anti-parallel to the electric field (i.e. the angle between the dipole moment and the electric field is 180∘).
What is the electric flux through the Gaussian surface containing two electric dipoles?
– The electric flux through a Gaussian surface is equal to 1/ε₀ times the net charge enclosed by it. – As the net charge is zero in the case of a dipole, so the electric flux passing through the surface will be zero.
What is flux of electric field?
electric flux, property of an electric field that may be thought of as the number of electric lines of force (or electric field lines) that intersect a given area. … The negative flux just equals in magnitude the positive flux, so that the net, or total, electric flux is zero.
What is the relationship between electric field and electric flux?
Electric flux is the rate of flow of the electric field through a given area (see ). Electric flux is proportional to the number of electric field lines going through a virtual surface.
What is the electric flux through the cube face s1?
Answer: Explanation: electric flux will be zero. it is given that, electric field, E = 3 × 10³ i N/C through a square of side 10cm.
