Question

The radius of the first orbit of hydrogen atom is 0.5 Å. The electron moves in an orbit with a uniform speed of 2.2 x 10⁶ ms^-1. What is the magnetic field produced at the centre of the nucleus due to the motion of this electron? Use µ₀ = 4π x 10^-7 Hm^-1 and electric charge = 1.6 x 10^-19 C

Answer 1

Here, r = 0.5 Å = 0.5 x 10^-10 m 

v = 2.2 x 10⁶ ms^-1 

Period of revolution of electron

= 1.12 x 10^-3 A

Magnetic field produced at the centre of the nucleus,

B = 14. 07 T
