Coulomb's law applies exactly only when the charged bodies are much smaller than the distance separating them and therefore can be treated approximately as point charge

Why is B the symbol for magnetic induction?
When the magnetic field is observed from the North pole, the magnetic field emerges and and goes towards south. However, inside a magnet there is no field at all, thus forming butterfly shape lines. Hence, B stands for butterfly and due to this concept, scientists used the symbol B for magnetic induction.
Why a dipole develops in a molecule?
a dipole develops in a molecule due to unequal sharing of electrons.
Is limestone magnetic?
No, the limestone is not magnetic due to the magnetic fields in the stone itself.
What is the difference between instantaneous dipole and induced dipole?
Dipole-dipole is between two polar molecules, that would be polar anyway. Dipole-induced dipole is between a polar molecule and a non-polar molecule that is now polar due to the proximity of a polar molecule.
What is the intermolecular force of acetone?
dipole-dipole and dispersion forces similar to water without hydrogen bonding as hydrogen is not bonded directly to oxygen. note: oxygen has 2 lone pair in both acetone and h2o.
What is difference between between electric dipole moment and magnetic dipole moment?
Magnetic dipole is due to two poles of magnet. Electric dipole is due to +ve and -ve charges of electric charges.

Difference between inductance and inductive reactance?
The opposition to AC current flow in a circuit due to induction is called inductive reactance.The process of generating electrical current in a conductor by placing the conductor in a changing magnetic field is induction or just induction.
What is the nature of symmetry of a field due to a dipole?
the nature of symmetry of a field due to a dipole is cylindrical in nature
Electromagnetic induction occurs in a coil when there is a change in?
Could you specify "coil"? Generally the electromagnetic induction occures due to variation of the B-field (magnetic flux density), variation of the current, I, or a change in the total area in which an electric current span over a B-field.
Why a dipole develops in a molecule?
a dipole develops in a molecule due to unequal sharing of electrons.
What is secondary embryonic induction?
Induction due to grafted tissue .
What is Dipole - Dipole interaction?
When a polar and a non-polar molecule come close the attraction taking place between them due to partial charges isknown as dipole induced dipole interaction.
What intermolecular forces exist between two SO2 molecules?
Dipole-Dipole as SO" is a bent molecule with a dipole momennt (1.62D) due to the electronegativity dfference between S and O. There will also be weaker London dispersion forces due to instantaneous dipoles.
What is induction motor in physics?
An induction motor consists of a rotor winding and stator winding. Rotor windings are short circuited and stator winding are given electrical AC supply .Now lets do the physics behind it . As the current starts to flow in the stator winding , magnetic flux start to produce around it . due to it's alternating nature that flux varies and according to farady law emf is induced in the rotor winding .Since the rotor winding is short circuited the current circulates in it .And when a current carrying conductor is placed in magnetic field it experiances a force and hence if start to rotate.
Why is ph3 Dispersion and Dipole-Dipole?
PH3 has a dipole moment , of 0.58 D. Therefore there will be dipole dipole interactions. All molecules experience London dispersion forces as these are caused by the interaction of instantaneous dipoles due to the movement of electrons within the molecules.
What is the total charge on an electric dipole?
Q1:How to calculate electric potential due to a dipole? Q2:How to calculate electric potential due to ring of charges? Q3:How to calculate electric potential due to charge disk? Q4:how to calculate electric potential due to a quadrupole?
