55.In the hydrogen atom, an electron makes a transition fromn-2 ton-1. The magnetic field produced by the circulatingelectron at the nucleus(a) decreases 16 times(c) decreases 4 times(b)(d)increases 4 timesincreases 32 times

Answer»

since the formula of bohr radius = 0.529n²/z

so, r ∞ n²

also, magnetic field ∞ 1/r=> magnetic field ∞ 1/n²

so when n changes from 2 to 1magnetic field changes from 1/2²= 1/4 to 1

so , it increases 4times..

option B

But ans is d

Here i is not also constant value..... So itink i must e resolve. In n relationship

I don't think.. answer should be d..how can it increase by 32times..

Use it

Thanks anjum
