Axial line is the line joining the centres of positive and negative charges forming an electric dipole. Consider an electric dipole consisting of +q and -q charges separated by a distance 2l.
What is axial position 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.
What is axial line in electric dipole?
The axial line of a dipole is the line passing through the positive and negative charges of the electric dipole. … An equatorial line of a dipole is the line perpendicular to the axial line and passing through a point mid way between the charges. Consider a dipole consisting of -q and +q separated by a distance 2a.
What is axial and equatorial position in physics?
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.
What do you mean by axial field?
The distance along the body axis which can be imaged at one bed position by the scanner’s detector geometry. (
What is SI unit of electric dipole moment?
The SI units for electric dipole moment are coulomb-meter (C⋅m); however, a commonly used unit in atomic physics and chemistry is the debye (D).
What do you mean by electric dipole?
An electric dipole is defined as a couple of opposite charges q and –q separated by a distance d. … The simplest example of an electric dipole is a pair of electric charges of two opposite signs and equal magnitude separated by distance.
What is the direction of electric field due to an electric dipole at axial line?
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.
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.
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 axial or equatorial more stable?
A conformation in which both substituents are equatorial will always be more stable than a conformation with both groups axial.
What is axial and equatorial?
The bonds to non-ring atoms are termed axial or equatorial, depending on the bond angle. Bonds to non-ring atoms with angles of about 90° to the ring plane are termed axial. Bonds to non-ring atoms which make only a small angle compared with the plane of the ring are termed equatorial.
What is the formula of equatorial line?
Distance AB = 2a, O is the mid point of the dipole and OP is perpendicular to AB. A charge Q is placed at P where OP = y and y >> 2a. The charge Q experiences and electrostatic force F. If Q is now moved along the equatorial line to P’ such that OP′=(3y) the force on Q will be close to L : (3y>>2a)
What is the value of e Axial?
E = 14πε0 2Pr2.
