# 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.
