What is an equatorial line of electric dipole?

What is an equatorial line of electric dipole?

A line perpendicular to the axial line and passing through the midpoint of electric dipole is called its equatorial line. Consider a point P on the equatorial line of an electric dipole (situated in a vacuum) at a distance r from the midpoint O of the electric dipole of length 2a as shown in figure.

What is axial line and equatorial line of a dipole?

Axial line is the line which is passing through the positive and negative charges and the point lies on that line is called the axial point. Equatorial line is the perpendicular line to the line passing through the positive and negative charges and the point lies on that line is known as the equatorial point.

Which is zero at equatorial position of an electric dipole?

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

What is the relation between electric field on axial line and equatorial line when dipole is of very short length?

Explanation: The electric field at an axial point of the short dipole is →E1if the electric field at equatorial point of the same dipole is →E2, then which of the following is correct. A) →E1.

What is axial line of a dipole?

A line passing through the positive and negative charges of the dipole is called the axial line of the electric dipole. Consider a point P on the axial line of a dipole (situated in a vacuum) of length 2a at a distance r from the midpoint O.

Why is Equatorial potential zero?

Since net potential is algebraic sum of potential due to both positive and negative charges in dipole. Further at equatorial position distance from both the charges is same, so net potential is zero.

When the point P lies on an equatorial line of the dipole the potential is?

Answer: If the point P lies on the equatorial line of the dipole, then θ = 90°. Hence, V = 0.

What is the direction of electric field intensity at a point on equatorial line of dipole?

EXPLANATION:​ For a point on the equatorial line of the dipole, the direction of electric field (E) is along a line parallel to the axis of dipole directed opposite to the direction of dipole moment (P) and is perpendicular to the equatorial line. Therefore option 3 is correct.

What is the relation between electric field due to a dipole in axial and equatorial line?

The line perpendicular to the axial line and passes through the centre of the electric dipole length is called an equatorial line. Consider an electric dipole AB consisting of +q and -q charges separated by a distance 2l. Let P be the point on the equatorial line at a distance r from the centre O of the dipole.

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 is electric dipole and find the electric potential on equatorial point of the dipole?

Therefore, the electric potential due to an electric dipole at a given point is equal to KPcosθr2−a2cos2θ. Hence, V=KPcos(π2)r2−a2cos2(π2)=KP(0)r2−a2(0)=0. Therefore, when the given point is on the equatorial axis, the electric potential is zero.

When the point P lies on the equatorial line of the dipole 90 and COS 0 then VP?

What is equatorial line of electric dipole?

A line perpendicular to the axial line and passing through the midpoint of electric dipole is called its equatorial line. Consider a point P on the equatorial line of an electric dipole (situated in a vacuum) at a distance r from the midpoint O of the electric dipole of length 2a as shown in figure.

What is an electric dipole moment?

The electric dipole moment associated with two equal charges of opposite polarity separated by a distance ‘d ’ is defined as the vector quantity having a magnitude equal to the product of the charge and the distance between the charges and having a direction from the negative to the positive charge along the line between the charges.

What is the center of the dipole called?

The midpoint q and –q is called the centre of the dipole. The simplest example of an electric dipole is a pair of electric charges of two opposite signs and equal magnitude separated by distance.

When the dipole is parallel to the field the torque is?

When the dipole is parallel to the field, the torque on a dipole is minimum. Give an example of the electric dipole. A pair of electric charge of two opposite signs and equal magnitude separated by a distance. Stay tuned with BYJU’S to learn more Physics concepts with the help of interactive video lessons.
