# At what position electric field is zero in case of electric dipole?

Contents

In Region II, between the charges, both vectors point in the same direction so there is no possibility of cancelling out. In Region III, the fields again point in opposite directions and there is a point where their magnitudes are the same. It is at this point where the net electric field is zero.

## Where is the electric field zero for an electric 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.

## At what position is the electric dipole in uniform electric field?

Even if we change the orientation, the length and the charge of the dipole, the net force on the dipole will be equal to zero. Hence, the electric force on a dipole when it is placed in a uniform electric field is always zero. So, the correct answer is “Option A”.

## Which is zero at equatorial position of an electric dipole?

Consider a point P situated on the equatorial line of the electric dipole at a distance r from mid-point of dipole. V=VA+VB=-q4πε0√r2+a2+q4πε0√r2+a2=0 . hus, potential at any point on equatorial line of an electric -9. dipole is zero irrespective of the position of that point.

## Is electric potential zero when electric field is zero?

Because in an equipotential surface the potential at all the points are same. So,E=0. Yes, Electric Potential is zero at a particular point, it does not necessarily mean that the electric Field is also zero at that point. It can be understood with the Case of Electric Dipole.

## What is electric field direction?

The direction of an electrical field at a point is the same as the direction of the electrical force acting on a positive test charge at that point.

## At what position is the electric dipole in uniform electric field in its I most stable position and II unstable equilibrium?

A dipole placed in a uniform electric filed is in Stable equilibrium when the electric field is directed along the direction of the dipole i.e., when is parallel to. Unstable equilibrium when the electric filed is directed at an angle of 180 degrees with the direction of the dipole, i.e., when is anti-parallel to.

## Why the net force on dipole is zero?

When a dipole is immersed in a uniform electric field, as illustrated in Figure 16.4. 3, the net force on the dipole is zero because the force on the positive charge will always be equal and in the opposite direction from the force on the negative charge.

## What is electric potential at equatorial point?

Therefore, when the given point is on the equatorial axis, the electric potential is zero.

## What is electric potential at a equatorial point of small dipole having dipole moment p?

Electric potential at an equatorial point of a small dipole with dipole moment p (r, distance from the dipole) is. zero.

## At what point’s on the line joining the two charges is the electric potential zero?

At what point(s) on the line joining the two charges is the electric potential zero? Take the potential at infinity to be zero.

## How is electric field zero?

To find where the electric field is 0, we take the electric field for each point charge and set them equal to each other, because that’s when they’ll cancel each other out. The ‘s can cancel out. Therefore, the electric field is 0 at .
