Where is the electric field zero in a dipole?
There is a spot along the line connecting the charges, just to the “far” side of the positive charge (on the side away from the negative charge) where the electric field is zero.
What is the direction of electric field at the Centre of an electric dipole?
In the middle of the dipole, the electric fields contributed by both charges are in the same direction; they are both pointing toward the negative charge. Thus, the magnitude of the electric field is the sum of the contribution of the two charges.
What is the electric field inside a sphere?
Thus outside the sphere, the electric field behaves as though it is due to a point charge (carrying all the charge of the shell) at the centre of the shell….Recommended Video.

What is the potential at the Centre of the sphere?
For the electric potential at the centre Vcentre, x=0. Hence, the potential at the centre is greater than the potential at any other inside point. Now, for the electric potential at the surface Vsurface, x=R. Hence, the electric potential at the surface is lesser than that at any inside point.
What is the direction of dipole moment for a dipole?
Answer: The direction of dipole moment is from negative to positive charge.
What is a dipole in an electric field?
A pair of electric charges with an equal magnitude but opposite charges separated by a distance d is known as an electric dipole. The electric dipole moment is a vector having a defined direction from the negative charge to the positive charge. …
What is the potential at the Centre of a sphere?
It will mainly depend on the charge distribution inside the sphere. But if the charge distribution is uniform throughout the sphere then the electrostatic potential at the center will be zero.
What is the electric potential at its center?
Electric potential at the centre of the ring is the same as the potential due to a point charge. Whereas the electric field is 0 at the centre of the ring because the electric field at the half side of the ring cancels out the other half.
Which dipole is placed at the centre of a sphere?
An electric dipole is placed at the centre of a sphere. Mark the correct answers : The flux of the electric field through the sphere is zero. The electric field is zero at every point of the sphere. The electric potential is zero everywhere of the sphere. The electric potential is zero on a circle on the surface.
Can electric field be zero at every point of a sphere?
According to Gauss’s law,electric flux depends only on the charge inside the sphere. As the net charge of dipole is zero, so the flux through the sphere is zero. But the electric field is the resultant effect due to all charges. So the electric field can not be zero at every point of sphere.
What is the flux of the electric field through the sphere?
The flux of the electric field through the sphere is zero. D The electric potential is zero on a circle on the surface. According to Gauss’s law,electric flux depends only on the charge inside the sphere. As the net charge of dipole is zero, so the flux through the sphere is zero.
What is the electric field due to a small dipole?
The electric field due to small dipole, at point (r, theta), where r is distance from center of the dipole and (theta) is angle between r and dipole]
