What is the relation between electric field on the axial line of a dipole and on the equatorial line of dipole?
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.
What is the relation for electric field intensity at the axial line of an electric dipole?
Let P be a point on the axial line of the dipole. Let the distance of point P from the midpoint of the dipole be r such that r>>>a. The electric field at point P will be due to the two charges on the given dipole. The magnitude of electric field due to the charge +q will be E+q=kq(r−a)2.
What is the relation between electric field on axial line and equatorial line when dipole is of very short length?
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 the relation between axial and equatorial electric field?
Axial line – A line joining the two charges and passing through the centre of dipole is called its axial line. Equatorial line- A line passing through the centre of the dipole and perpendicular to the axial line is called equatorial line.
What is meant by electric field intensity?
A measure of the force exerted by one charged body on another. The electric field intensity (volts/meter) at any location is the force (Newtons) that would be experienced by unit test charge (Coulombs) placed at the location. …
What is electric field at Axial point?
Electric field due to an electric dipole at a point on its axial line: AB is an electric dipole of two point charges −q and +q separated by small distance 2d. P is a point along the axial line of the dipole at a distance r from the midpoint O of the electric dipole.
What is the expression for electric field?
In vector calculus notation, the electric field is given by the negative of the gradient of the electric potential, E = −grad V. This expression specifies how the electric field is calculated at a given point. Since the field is a vector, it has both a direction and magnitude.
What is the angle between electric field and dipole moment on the axial line?
the angle between electric dipole moment and electric field strength due to dipole on axial line is 180°.
Can electric field be negative?
Electric field is not negative. It is a vector and thus has negative and positive directions. An electron being negatively charged experiences a force against the direction of the field. For a positive charge, the force is along the field.
Is electric potential zero when electric field is zero?
Yes, electric potential can be zero at a point even when the electric field is not zero at that point. … At the midpoint of the charges of the electric dipole, the electric field due to the charges is non zero, but the electric potential is zero.
What is axial point?
axial point (plural axial points) (mathematics) Any point that lies on any of the axes of a coordinate system. (optics) nodal point.
