Calculate the orb

Answer :

Orbital period can be calculated as:


T1 = (2πr1)/v1


Where r1is the radius of the orbit and is given as follows:



Where ε0 is the absolute permittivity of free space and is given as = 8.854 × 10-12 N-1C2m-2


h is Planck’s constant and is given as 6.64 × 10-34 Js


e is charge on an electron and is equals to 1.6 × 10-19C


m is the mass of an electron, and is equals to 9.1 × 10-31 Kg


substituting the values, we get



On calculating, we get


T1 = 15.27 × 10-16 seconds


For n = 2, we get



On calculating, we get


T2 = 1.22 × 10-15 seconds


For n = 3, we get



On calculating, we get


T3 = 4.12 × 10-15 seconds.
