Write down a short note on the discovery of neutron. Show the uses of radioisotopes.
The contribution of ionic polarization takes account of the fact that when in a molecule some of the atoms have an excess positive or negative charge (resulting from the ionic char
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
