Bohr given a model for hydrogen molecule which is also applicable for some lighter atoms in which a one electron revolves around a stationary nucleus of positive charge Ze (known as hydrogen like atom)
Bohr's model is based on the following postulates.
(i) The electron can revolve only in particular discrete non-radiating orbits, named stationary orbits, for which total angular momentum of the revolving electrons is an integral multiple of
Light is shined into a glass rod. To guarantee the total internal reflection (TIR) happens to all the possible rays, what is the minimum index of refraction n for the glass?
Coulomb: Coulomb is the fundamental unit of charge. It is explained as the charge required to obtain 9?109 newton of force among two equal charges separated at a distance of one m
Gauss' law: The electric flux by a closed surface is proportional to the algebraic total of electric charges contained in that closed surface; in differential form, div E =

what is poission''s equation?Establish poisson''s equation for space distribution of charges.discuss its significance.
The molecular theory of magnetism was given by Weber and modified later by Ewing. According to that theory - Each molecule of a substance is a complete magnet in itself. Though,
Two concentric conducting shells a and b are of radii R and 2R. A charge +q is centred at their center. Shell b is then earthed and a is given charge q. Find the charge on outer su
