Why the direction of dipole is from negative to positive?

Why the direction of dipole is from negative to positive?

showing that the dipole moment vector is directed from the negative charge to the positive charge because the position vector of a point is directed outward from the origin to that point. (Because of overall charge neutrality, the dipole moment is independent of the observer’s position r.)

Can a dipole moment be negative?

The convention in chemistry is that the arrow representing the dipole moment goes from positive to negative. Physicist tend to use the opposite orientation. The vector points from positive to negative, on both the molecular (net) dipole moment and the individual bond dipoles.

Why electric dipole moment is a vector quantity?

It is a vector since it points in one direction (from one charge to the other), has an associated magnitude and so on. In a way, when you consider a multipole expansion it makes sense, the monopole momentum is just the net charge (a scalar), the dipole momentum a vector and from then on matrix quantities.

Is electric dipole moment vector quantity?

Electric dipole moment is a vector quantity and it is represented as →p=q×→d in vector form. Here p is the dipole moment, q is the charge and d is the distance and direction of →dis from negative charge to positive charge.

What is electric flux through a cube of side 1 cm?

Therefore, the net charge enclosed within the cube is zero. Therefore, electric flux is zero.

What is the flux through cube of side A?

According to gauss law, the electric flux through a closed surface is equal to qε∘, if q is the charge enclosed in it. If the charge ‘q ‘is placed at one of the corners of the cube, it will be divided into 8 such cubes. Therefore, electric flux through the one cube is the eighth part of qε∘.

What is the magnitude of the electric flux through the frame?

The magnitude of the electric flux through this frame is Φ0. A second frame is placed in the same electric field in such a way that the magnitude of the electric flux through it is Φ0/2.

What is the electric flux passing through two opposite faces of the cube?

0 Two faces of the cube comprises 1/3 of the total surface of the cube. Therefore, the flux through two faces is, q/3? 0.

What will be the total flux through the faces of the cube with side of length A?

1 Answer. 8 cubes. Therefore, total flux through the faces of the given cube =q/8ϵ0.
