Why the electric potential on the equatorial line of an electric dipole is zero?
Another question that electric potential at infinity is 0. So if I bring a positive charge from infinity to the equatorial point of the dipole then the work done by me to bring it is 0.
What is the electric potential at point on the equatorial line of an electric dipole?
Electric potential at any point in the equatorial plane of dipole is zero.
How we can explain potential at any point on the equatorial line of dipole is zero find the minimum and maximum value of magnitude of the potential of a dipole?
The potential at a point due to an electric dipole will be maximum and minimum when the angles between the axis of the dipole and the line joining the point to the dipole are respectively. V=pcosθr2. If θ=0∘ then Va=max. If θ=180∘ then Ve=min.
What are the points at which electric potential of a dipole has a zero value?
(ii) At equatorial points, the electric potential of a dipole is zero.
In which orientation is potential energy of an electric dipole zero in a uniform electric field?
90°
From the above equation, we can see that the potential energy of dipole placed in an external field is zero when the angle Ɵ is equal to 90° or when the dipole makes an angle of 90°.
At what angle the potential energy of the electric dipole is minimum?
When the angle between the dipole moment and electric field is zero then the potential energy of electric dipole is minimum.
How does electric potential due to a dipole vary with distance?
Explanation: For an electric dipole (at large distances), The electric potential varies inversely with the square of the distance. For a point charge, The electric potential varies inversely with the distance.
What is the electric potential of an equatorial dipole?
Therefore, on equatorial position net charge is zero, q=0. This implies that no work will be done in moving a charge along the equitorial line of the dipole. This implies that electric potential will be zero.
Is electric potential a scalar or vector quantity?
Electric Potential is a scalar quantity. On equatorial position of the dipole, the distance from the positive charge and the negative charge is equal and they have equal, but opposite magnitude. Therefore, on equatorial position net charge is zero, q=0.
What is the net electric field of a dipole?
at any segment of the equatorial line say dy ,the effective field of forces or the net electric field is sum of the two forces acting due to the two charges of the dipole, which are opposite in character but equal in magnitude – so if the effect of one is attractive then the effect of other one of the pair will be repulsive…
What is the direction of the test charge on a dipole?
It is, in fact, purely in the direction of the dipole (i.e. a test charge would repel from the positive end and go to the negative end) and it is 0 in the direction of this perpendicular bisector.
