Question

At what speed must the must the electron revolve the nucleus of hydrogen in ground state in order that it may not be pulled into the nucleus by electrostatic attraction

Answer 1

Answer:

Using these values along with the dielectric constant of free space to be 8.854 x 10 {+-} {+1}{+2} Farad per meter, it is possible to make an estimate of the speed of the electron in the circular orbit of the hydrogen atom to be about 2.188 x 10 {+6} meters per second or 2188 km/sec.
