Prove that u(n) = sqrt((Zn^(2))/(mr(n)))...

Prove that `u_(n) = sqrt((Zn^(2))/(mr_(n)))` where n is the Z at distance r_(n) from the m and r mass and charge of electron

Text Solution

Verified by Experts

kinetic energy of electron `== (1)/(2) ma^(2)`
Also from Bohr's concept
`KE = (1)/(2) (Ze^(2))/(r_(n))`
`:. (1)/(2) "mu"^(3) = (1)/(2) (Ze^(2))/(r_(n))`
`a = sqrt((Ze^(2))/(mr_(n)))`
