A. - 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 ...
Potential Energy of a Dipole of Dipole Moment p in a Uniform Electric Field: E = –p.E. Equipotential Surface: An equipotential surface is a surface over which potential has a constant value. For a point charge, concentric spheres centered at a location of the charge are equipotential surfaces.
Magnetic dipole moment:- It is defined as the product of its pole strength and magnetic length. a) The force on it is zero. b) The torque on it is c) Torque on dipole will be minimum when = 0 o d) Torque on dipole will be maximum when = 90 o. When a bar magnet of dipole moment is placed in a uniform magnetic field , then-e) Its potential energy is
