What is an ideal electric dipole and what is meant by a permanent dipole?
Asked by NAKSHATRA | 25th Jul, 2014, 08:18: AM
A pair of equal and opposite charges seperated by a small vector distance is called an electric dipole.
An ideal dipole consists of two very very large charges + q and - q seperated by a very very small distance.
An ideal dipole has almost no size.
Molecules are made up of positive and negative charges seperated by small distances like water, ammonia etc and they act as electric dipoles.
Molecules which have non uniform distribution of charge are known as polar.Polar molecules will always be slightly negative on one end and slightly positive on the other Polar molecules are said to be permanent dipoles.
Eg: water, carbon dioxide.

- the electric field at a point on the axial line at a distance of 10cm from the centre of an electric dipole is 3×10³NC·¹ in air while at a diatance of 15cm,the electric field is 2×10³NC·¹ Calculate the length of an electric dipole. 3×10³NC·¹
- An electric dipole moment 4x10^-9 cm is aligned at 30°with the direction of a uniform electric field of magnitude 5x10^4 NC^-1.calculate the magnitude of the torque acting on the dipole?
- Determine electric field at a point p for two identical dipole placed along x and y axis with dipole moment p and angle 45°
- An electric dipole is formed by two particles fixed at the end of a light rod of length L. Mass m and 2m with charge q and - q. The system is placed in such a way that the dipole axis is parallel to a uniform electric field. If the dipole is slightly rotated about its center then show that for small angular displacement it's an shm. And find time period
