Electrostatic is the study of charge particle when they are in rest. Here we introduced with negative and positive charges. How they are produced and what are their properties.
Electric charge and field note - Electric charge is the fundamental characteristics of the elementary particle who explain the force of interaction between the particle and the interaction energy
Coulomb's law -This law states that the force of attraction or repulsion between the two electric charges.'k' the proportionality constant is called Coulomb's law constant.
Electric field -Electric line of force are the imaginary line, draw from the positive chrge to the negative charge.
Electric line of force also define here.
Electric dipole -- A electric dipole consist of a combination of two equal and opposite charges situated very close to each other.
Electric field due to dipole at any point, electric field due to dipole at equatorial Point. Dipole moment - Electric dipole moment of a electric dipole is defined as the product of magnitude of each charges and the separation between them.
Electric dipole in a uniform electric field -An electric dipole in a uniform electric field does not experience a force. It experience only torque.
The torque acting on a dipole is perpendicular to the plane containing electric dipole moment P and the electric intensity E of the field.
Electric flux -The electric flux is the dot product of electric field and surface area vector.
Area vector -The electric flux is the dot product of electric field and surface area vector.
Gauss's law -It state that, for any distribution of charges , the total electric flux link with a close surface is 1/(epsilon not) times of the total charge enclosed by the surface.
Electric potential -Electric potential is define as the amount of work required to move a unit positive charge from infinity to that point,with out any acceleration, against the electric force .
Electrostatic class 12th bord question With answer
Equipotential surface - An Equipotential surface is defined as the locus of all points in a medium at which the potential due to charge distribution is same.
Electric potential energy - Electric potential energy of a system of point charges is the workdone require to bring a charge from infinity to their final position.
