    In this case....whatever be the nature or value of the charge'q' .It will always remain in equilibrium. It is sk because the net force acting on the charge q is always zero. (k•q•Q)/(x)^2=(k•q•Q)/(x)^2

    Beacause if it is r^3 then this becomes volume(3d) instead of area(2d) so the electric flux get affected and if the flux get affected then gauss law is also affected

    0Thank You

    Abhishek Vishwakarma 3 hours ago

    Gauss' Law gives the number of electric field lines paasing perpendicular through a unit area.So it is independent of Coulomb's Law which gives the magnitude and direction of the electrostatic force.Therefore there would be no effect on gauss law.However the numerical value of flux may change.

    Polarised light:

    1. The vibrations of light (vibrations of the electric vector) are restricted in a particular plane.

    2. It is absolutely coherent in nature.

    3. In polarized light, electric vector is confined to a plane and magnetic vector H is normal to the plane

    Unpolarised light:

    1. The vibrations of light (vibrations of the electric vector) occur in many plane i.e., it is not restricted to a particular plane.

    2. It is incoherent in nature.

    3. In unpolarized light, the plane of vibration of electric vector is continuous.
