What is electric dipole ? Write its SI unit. |
|
Answer» Solution :An electric DIPOLE is a system of TWO equal and opposite point charges separated by a finite distance. If .2a. is the distance betweentwo charges q and `-q` the dipole MOMENT of this system is given by `vecp =q(2veca)`Electric dipole moment is a vector quantity, its direction is pointing towards POSITIVE charge.  The unit of electric dipole moment is Cm (Coulomb-meter) or Ampere-second meter. Its dimensional formula is `M^(0)L^(1)T^(1)A^(1)` and `M^(0)L^(1)T^(0)Q^(1)`. Total charge of the dipole system is zero. But its electric field is non-zero because two opposite charges are situated at DIFFERENT places. |
