What is the nature of electric field for point charge and electric dipole?

The electric field due to a point charge has spherical symmetry with point charge at the center, It is so because, the electric field due to dipole will be same at every point on the surface of a right circular cylinder with electric dipole as sthe axis.

What is the nature of symmetry of electric field due to point charge and electric dipole?

So, the electric field due to a point charge is spherically symmetric. Now, imagine a cylinder of radius r drawn with electric dipole as axis. The electric field, due to dipole, at all points on the surface of the cylinder will be the same. So, the electric field due to dipole has cylindrical symmetry.

What is the difference between an electric field due to a point charge and a dipole?

An electric dipole is a system of two equal and opposite point charges separated by a small distance. An electric field due to a charge is the space around the charge in which any other charge experiences a force of attraction or repulsion.

What is symmetry of electric field?

Symmetry and Electric Fields

An electric field has the same symmetries as the source charges that created it. … Thus the electric field at any point on the plane cannot have a Z-component: it must point along the plane.

GOOD TO KNOW:  Quick Answer: What is the function of electrical stage?

Can an electric field be zero?

For like charges, the electric field will be zero closer to the smaller charge and will be along the line joining the two charges. For opposite charges of equal magnitude, there will not be any zero electric fields.

Can electric field intensity be negative?

An electric field can never be negative. An electric field is a force experienced by the charge divided by the magnitude of the charge. The magnitude of the charge is the modulus value of the charge.

What are electric fields used for?

The electric field lines flow from positive to negative charges. Such sources are well suited for surface applications such as wound healing, corneal repair or even brain and spinal stimulation with closely-separated, inserted electrodes.
