Suppose an electron is attracted toward the origin by a force`(k)/(r )` where `k` is a constant and `r` is the distance of the electron from the origin .By applying Bohr model to this system the radius of the `n^(th)` orbital of the electron is found to be `r_(n)` and the kinetic energy of the electron to be `T_(n)` , Then which of the following is true ?A. `T_(n) prop 1/(n^(2)),r_(n) prop n^(2)`B. `T_(n)` independent of `n, r_(n) prop n`C. `T_(n) prop 1/n, r_(n) prop n`D. `T_(n) prop 1/n, r_(n) prop n^(2)` |

Answer» Correct Answer - B `k/r=(mv^(2))/r implies mv^(2) =k` (independent or r) `n(h/(2pi))=mvrimplies r prop n` and `T=1/2 mv^(2)` is independent of n. |
