Question

Define the following terms with the help of a diagram.

i. Electric dipole 

ii. Dipole axis 

iii. Axial line 

iv. Equatorial line

Answer 1

i. Electric dipole: A pair of equal and opposite charges separated by a finite distance is called an electric dipole.

ii. Dipole axis: Line joining the two charges is called the dipole axis.

iii. Axial line: A line passing through the dipole axis is called axial line.

iv. Equatorial line: A line passing through the centre of the dipole and perpendicular to the axial line is called the equatorial line.

AB : Electric dipole Line joining 

AB : Dipole axis 

X-Y : Axial line 

P-Q : Equatorial line
