Explain axial field or electric field on the axial line of an electric dipole i.e. end on position. A line passing through the positive and negative charges of the dipole is called the axial line of the electric dipole. Let overrightarrow{E} be the resultant electric intensity at P. Besides, what is axial line in physics?
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.
Secondly, what is equatorial line? An equator is an imaginary line around the middle of a planet or other celestial body. It is halfway between the North Pole and the South Pole, at 0 degrees latitude. An equator divides the planet into a Northern Hemisphere and a Southern Hemisphere. The Earth is widest at its Equator.
Similarly one may ask, what is the angle between E and P on the axial line?
Electric field at equatorial point and axial point are always antiparallel so angle is 180 degrees.
What is the direction of electric field at a point on axial line of an electric 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.
