In which orbit of the hydrogen atom is the speed of the electron maximum?

(a)
n
= 2 (b)
n
= 1 (c)
n
= 3 (d)
n
= 4

For an electron, the product
vn
(velocity x principal quantum number) will be independent of the

(a) principal quantum number

(b) velocity of the electron

(c) energy of the electron

(d) frequency of its revolution
