ke2/r2 = mv2/r
Where ke2/r2 is the Coulomb's force and mv2/r is the centripetal force of the electron around the nucleus
you know from Bohr's postulate
mvr = nh/2π
Combine the two equations. What is the value of the radius of the first orbit ?
r =Plank's constant h= 6.624 10-34 Js
electron mass me= 9.11 10-31 Kg
electron charge e= -1.6 10-19 C
Coulomb's constant k=8.99 109 m2N/C2

the values are given here like H=6.63×10 Js nd mass of electron =9.9×10k/g charge of electron=1.6×10C
its like of 30 marks and how should it be answered i have no idea
