Find the Central Force on an Electron in a Hydrogen Atom

[directdelta]

In the Bohr model of the hydrogen atom,
the speed of the electron is approximately
1.96e+6 m/s.
Find the central force acting on the electron
as it revolves in a circular orbit of radius
4.8e-11 m. Answer in units of N.

One could use the Coulomb force calculation and angular acceleration * mass (centripetal force) and compare the two.

thanks astronuc, but that did not help. i was talking about the "central force", not "centripetal" and again, the mass of the particle is not given, so i can't use the mass.
