In hydrogen atom an electron is making 6.6 10¹⁵ rev / s around the nucleus of radius 0.47 Å . The magnetic field induction produced at the centre of the orbit is nearly
Options
- A0.14 w b m ~ m⁻²
- B1.4 wb m ⁻²
- C14 w b m⁻²
- D140 w b⁻²
Correct answer
C. 14 w b m⁻²
Step-by-step solution
In hydrogen atom, f =6.6 10¹⁵ H _ z , r =0.47 ~A ^ I = e T = ef =1.6 10⁻¹⁹ 6.6 10¹⁵=10.56 10^4 ~A Magnetic field at the centre of the orbit is B = ₀ I 2 r = 4 10⁻¹ 10.56 10⁻⁴ 2 0.47 10⁻¹⁰ =14 wbm ⁻²
