according to the bohr model of the hydrogen atom, what is the closest an electron can get to the nucleus? What is the farthest it can get from the nucleus? ( if the latter answer seems absurb, it might amuse you to know that it is the same value predicted by present-day quantum chemistry)

I am having a hard time to answer this please someone help. I search for th answer but I can't find it in my book
