What is the electric field intensity due to a dipole on its equatorial line?
Two equal and opposite charges seperated by some distance constitute a dipole. The electric field strength due to a dipole, far away, is always proportional to the dipole moment and inversely proportional to the cube of the distance.
What is electric field due to axial and equatorial dipole?
Therefore, the unit vector of the net electric field and the dipole moment vectors will be equal i.e. ˆE=ˆP. Now, the net electric is →E=2kP(1r3). ˆP. Hence, the electric field due to a dipole, at a given point on its axial line is →E=2kr3→P.
What is the electrostatic dipole at an equatorial point?
Derive an expression for the electric field at a point on the equatorial plane of an electric dipole. Hint: Dipole is a pair of equal and opposite charges separated by some distance. Dipole moment of a dipole is the product of the charge with the separation distance between two opposite charges.
What is electric field intensity due to dipole?
E acts in the direction of the dipole moment. Therefore, the expression for the electric field intensity due to an electric dipole at a point on its axial line is E=q4π∈∘. 2(2d)r3=14π∈∘.
What is the electric field intensity?
The electric field intensity at a point is the force experienced by a unit positive charge placed at that point. Electric Field Intensity is a vector quantity. … Formula: Electric Field = F/q.
What is the angle between electric field and dipole moment at an equatorial point?
On equatorial line, the direction of electric field is reversed to that of angle of axial line. Therefore, the angle between dipole moment and electric field is 180°.
What is the direction of electric field on axial point and Equatorial point due to a dipole?
Answer: THE DIRECTION OF ELECTRIC FIELD IS IN THE SAME DIRECTION AS DIPOLE DIRECTION (FROM NEGATIVE CHARGE TO POSITIVE CHARGE) IN AXIAL POINT BUT IN EQUATORIAL THERE IS A ANGLE DIFFERENCE OF 180° BETWEEN DIPOLE DIRECTION AND EQUATORIAL POINT DIRECTION (FROM POSITIVE CHARGE TO NEGATIVE CHARGE).
What is electric dipole Class 12?
The electric dipole is a pair of two equal and opposite charges, +q and −q are separated by a very small distance. … The electric dipole moment of the electric dipole is defined as the product of the magnitude of one of the charges of the dipole and the separation distance between them.
How is electric field of a dipole on equatorial line different from electric field due to a point charge?
The direction of the electric field at points on the dipole axis is directed along the direction of dipole moment vector but at points on the equatorial plane it is directed opposite to the dipole moment vector, that is along – . … Note that for a point charge, the electric field varies as 1/r2 .
What is the electrostatic potential due to an electric dipole at an equatorial point ?( No need of derivation?
Electric potential at any point in the equatorial plane of dipole is zero. a) An electrostatic field line is a continuous curve. That is, a field line cannot have sudden breaks.
