2.State coulombs law :
Coulombs law states that the force between any two point charges is directly proportional to the product of their magnitudes and inversely proportional to the square of the distance between them. It is directed along the line joining the two charges. F=Q1Q2 / 4ðår2 ar
3.State Gauss law for electric fields :
The total electric flux passing through any closed surface is equal to the total charge enclosed by that surface.
4.Define electric flux :
The lines of electric force is electric flux.
5.Define electric flux density :
Electric flux density is defined as electric flux per unit area.
6.Define electric field intensity :
Electric field intensity is defined as the electric force per unit positive charge.
E =F/ Q
7.Name few applications of Gauss law in electrostatics :
Gauss law is applied to find the electric field intensity from a closed surface.e.g)Electric field can be determined for shell, two concentric shell or cylinders etc.
8.What is a point charge :
Point charge is one whose maximum dimension is very small in comparison with any other length.
9.Define linear charge density :
It is the charge per unit length.
13.Define potential difference :
Potential difference is defined as the work done in moving a unit positive charge from one point to another point in an electric field.
14.Define potential :
Potential at any point is defined as the work done in moving a unit positive charge from infinity to that point in an electric field.
18. Define current density :
Current density is defined as the current per unit area. J= I/A Amp/m2
21.Write the boundary conditions at the interface between two perfect dielectrics :
i)The tangential component of electric field is continuous i.e)Et1=Et2
ii)The normal component of electric flux density is continuous I.e)Dn1=Dn2
23.What is meant by displacement current :
Displacement current is nothing but the current flowing through capacitor. J= D / t
24.State point form of ohms law :
Point form of ohms law states that the field strength within a conductor is proportional to the current density.
25 Define surface charge density :
It is the charge per surface area.
26.State amperes circuital law :
Magnetic field intensity around a closed path is equal to the current enclosed by the path.
27.State Biot –Savarts law :
It states that the magnetic flux density at any point due to current element is proportional to the current element and sine of the angle between the elemental length and inversely proportional to the square of the distance between them
29.Write down the expression for magnetic field at the centre of the circular coil :
H = I/2a.
30.Give the relation between magnetic flux density and magnetic field intensity :
B =µ H
31.Write down the magnetic boundary conditions :
i) The normal components of flux density B is continuous across the boundary.
ii) The tangential component of field intensity is continuous across the boundary.
