1.	The electron in a hydrogen atom jumps from ground state to the higher energy state where its velcoity is reduced to one-third its initial value. If the radius of the orbit in the ground state is `r` the radius of new orbit will beA. `3 r`B. `9r`C. `(r )/(3)`D. `(r )/(9)`
Answer» Correct Answer - B `v = (1)/(137)(c )/(n)` or `prop(1)/(n)` Since `v` is reduced to one-third therefore `n = 3` Now, `r prop n^(2)`.
