Question

According to bohr theory the angular momentum of electron in 4th orbit is

Answer 1

$\huge\mathfrak\red{Heya\:..!}$

The angular momentum (mvr) of electron in nth orbit is equal to nh/2π. Note: nh/2π gives angular momentum of electron revolving in a circular orbit as proposed by Neils Bohr. However orbital angular momentum of electron in a given orbital is calculated by using the following equation.

Answer 2

Answer:l = nh/2π

so 4th orbit = 4×h/2π

= 2h/π ans
