1.	Whichis are correct statement.A. The difference in angular momentum associated with the electron present in consecutive orbits of H-aom is `(n-1)(h)/(2pi)`B. Energy difference between energy levels will be changed If ,P.E. at infinty assigend value othe rthan zero.C. Frequncey of spectral line in a H-atom is in the order of`(2rarr1)lt(3rarr1)lt(4rarr1)`D. On moving away from the nucleus , kinetic energy of electron decreases.
Answer» Correct Answer - C::D Difference in angular momenture of consective orbits is=`(h)/(2pi)` Energy difference between two orbits its indendent of reference frequcecy of spectral line decrease on decreasing the difference in energy levels. On moving away speed & KE decreases as V `propto(1)/(r)`
