The electrostatic potential due to an electric dipole at an equatorial line at any point of that line is always zero. The potential on equatorial point due to charge of electric dipole is equal in magnitude but opposite in nature and hence the resultant is zero.
What is electric potential on an equatorial plane of an electric dipole?
Hence, the net potential at a point on the equatorial line of an electric dipole is zero.
Why is the electrostatic potential due to an electric dipole at an equatorial point is zero?
Actually the potential due to one charge of the dipole is just equal and opposite to that of due to other charge on any point on the equatorial line,therefore the potential of a dipole vanishes on any point on the equatorial line.
What is the electrostatic potential due to electric dipole?
What is the electric potential due to an electric dipole at an equatorial point? Zero, as potential on equatorial point, due to charges of electric dipole, are equal in magnitude but opposite in nature and hence their resultant is zero.
What is the electrostatic potential due to an electric dipole at a point?
Therefore, the electric potential due to an electric dipole at a given point is equal to KPcosθr2−a2cos2θ. Special cases: (i) When the given point is on the axial line of the dipole (i.e. θ=0).
What is the electrostatic potential due to an?
Electric potential of a point charge is V=kQr V = k Q r . Electric potential is a scalar, and electric field is a vector. Addition of voltages as numbers gives the voltage due to a combination of point charges, whereas addition of individual fields as vectors gives the total electric field.
Why is electrostatic potential constant throughout the volume of conductor?
Because there is no potential difference between any two points inside the conductor, the electrostatic potential is constant throughout the volume of the conductor. … This means there is no net charge at any point inside the conductor, and any excess charge must reside at the surface.
What is the Electric potential due to an electric?
Although the concept of electric potential is useful in understanding electrical phenomena, only differences in potential energy are measurable. If an electric field is defined as the force per unit charge, then by analogy an electric potential can be thought of as the potential energy per unit charge.
What is electrostatic potential at a point?
Electrostatic potential at any point in an electric field is defined as the amount of work done in bringing a unit positive charge from infinity to that point. Its unit is volt. Positive charges move from higher to lower potential regions.
What is the difference between electrostatic potential energy due to an electric dipole and due to charges?
Potential at a point due to single point charge depends only upon the distance r while due to an electric dipole depends upon the distance r and inclination of r. … Potential due to a single point charge varies as Voc while potential due to dipole varies as V.
What is electric field due to dipole?
Two equal and opposite charges separated by some distance constitute a dipole. The electric field strength due to a dipole, far away, is always proportional to the dipole moment and inversely proportional to the cube of the distance. Dipole moment is the product of the charge and distance between the two charges.
