Answer:
Let Z be the the atomic number of nucleus, then charge of nucleus is Z×e, where e is the fundamental charge.
Coulomb force FC and centripetal force FR are given by
Here r is radius of circular orbit, me is mass of electron and v is speed of electron.
Speed of electron v is obtained by equation FC and FR. Then we get the speed as
after substituting r=0.1 m and values for e, me and ε0 , we get v = 50×√Z m/s
