- 1Quantisation of Electric Chargeq = ne
- 2Coulomb's LawThe force of attraction or repulsion between two point charges is directly proportional to the product of the charges and inversely proportional to the square of distance between them
- 3One CoulombThe quantity of charge, which when placed at a distance of 1 metre in air or vacuum from an equal and similar charge, experience a repulsive force of 9x10^9 N.
- 4Electric Field Intensity (Electric Field Strength) or (Electric Field)*Electric field intensity at a point, in an electric field is defined as the force experienced by a unit positive charge kept at that point .
*Vector Quantity .
*Unit is - 5Electric Lines Of ForceIt is an imaginary straight or curved path along which a unit positive charge tends to move in an electric field
- 6Properties of Lines of Forces(i)+ve to -ve
(ii)Never Intersect
(iii)tangent to the line of force at any point gives the direction of electric filed at that point
(iv)no.of lines per unit area through a plane at right angles to the lines is proportional to the magnitude of E.
(v)Each unit positive charge give rise to 1/ ε0 lines of force in free space
