Suppose that in a parallel universe,the proton and electron were identical to their counterparts in our own universe EXCEPT that the electron had twice as much charge as our electron.In our present universe,the radius of the first Bohr orbit for hydrogen is a0 and the speed of an electron in that orbit is v0.In the parallel universe
(a)what would be the radius (in terms of a0)of the first Bohr orbit for hydrogen?
(b)what would be the speed (in terms of v0)of an electron in the first Bohr orbit for hydrogen?
