1.	Let r, v and E are the radius of the orbit, speed of the electron and the total energy of the electron respectively. Which of the following quantities are proportional to the quantum number .n. ?
Answer» `rE` `ur` `upsilon/E` `R/E` Solution :`upsilon = (2.188xx10^(-8))/(n)` CM/sec `r= n^2 XX 0.529 xx 10^(-8) cm , E=-(2.18 xx 10^(-18))/(n^2)` these relations shown that `upsilonr and (upsilon)/(E)` will be proportional to be principal quantum number n.
