What is the electric flux through a closed surface enclosing an electric dipole?

Answer: You can say that the electric flux will be zero as result of Gauss’s Law. Enclosing any number of charges who’s sum equals zero will result in a surface flux of zero.

What is electric flux through the Gaussian surface enclosing an electric dipole?

We have an electric dipole. … Now, the total charge enclosed by our Gaussian surface is zero, so according the Gauss‘ Law the flux through the Gaussian surface is zero, and so is the electric field intensity due the electric dipole.

When an electric dipole is held at an angle?

Answer: the forces experienced by the 2 charges constituting the electric dipole when placed in an uniform external electric field are equal and opposite in nature, the net force on the dipole is zero. No torque act on the dipole when the moment of electric dipole is parallel to the electric field.

What is the net electric flux through a closed surface?

The net electric flux is zero through any closed surface surrounding a zero net charge. Therefore, if we know the net flux across a closed surface, then we know the net charge enclosed.

How does electric field of an electric dipole vary with distance?

A short dipole is placed at the origin with dipole moment directed along positive x-axis. The electric intensity at a point P on x-axis, at distance much greater than the dipole length E. If the dipole is rotated clockwise by 90∘, why will be the value and direction of electric intensity at P (x,0).

What is electric flux through a closed surface?

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.

What is the formula of electric field of a dipole?

The formula for electric dipole moment for a pair of equal & opposite charges is p = qd, the magnitude of the charges multiplied by the distance between the two.

Are deflected in electric field?

X-rays are electromagnetic waves and are not charged. Neutrons are charge-less. Alpha particles are basically helium nuclei and are charged. So they are deflected in the electric field.
