Suppose the electron in a hydrogen atom makes a transition from $n = 3$ to $n = 2$ in $1 0^{- 8} s$ . The order of the torque acting on the electron in this period is:

Options:

Answer:

Solution:

$τ \sim \frac{Δ L}{Δ t} = \frac{( 3 - 2 ) ( h /2 π )}{1 0 ^{- 8}} \approx \frac{1.05 \times 1 0 ^{- 34}}{1 0 ^{- 8}} \approx 1 0^{- 26} N m$ .
