Chose the currect on the basis of Bohr's theory

Options

A. Velocity of electron `prop(1)/(n)`
B. frequancy of revolution `prop (Z^(2))/(n^(3))`
C. radius of orbit `prop n^(2)Z`
D. force on electron `prop (Z^(3))/(n^(4))`

Answer

A, B, D

Explanation

(A) `v=2.18xx10^(6)xx(Z)/(n)implies vprop(Z)/(n)` or `v prop(1)/(n)`
(B) `f=(v)/(2pir)` or `f=(v)/(r) prop (Z//n)/(n^(2)//Z)" "fprop(Z^(2))/(n^(3))`
(C ) `rpropn^(2)//Z " "[Tprop(n^(3))/(Z^(2))] " "F=(mV^(2))/(r )`
`F prop (v^(2))/(r ) prop ((Z^(2)//n^(2)))/(n^(2)//Z) " "F prop(Z^(3))/(n^(4))`
