1.	If the energy of an electron in 3rd Bohr orbit is -E, what is the energy of the electron in (i) 1stBohr orbit (ii) 2nd Bohr orbit ?
Answer» Solution :`E_(N) PROP (1)/(n^(2)) :. E_(3) prop (1)/(3^(2)) , " i.e., " E_(3) prop (1)/(9), E_(2) prop (1)/(2^(2)), " i.e., " E_(2) prop (1)/(4), E_(1) prop (1)/(1^(2))` `:. (E_(3))/(E_(1)) = (1)/(9) :. E_(1) = 9 E_(3) = - 9E "" ( :' E_(3) = -E)` `(E_(3))/(E_(2)) = (4)/(9) :. E_(2) = (9)/(4) E_(3) = - (9)/(4) E = -2.25 E`
