In hydrogen atom, an electron makes transition from n = 3 to n = 2 state in time interval of 1.2xx10^(-8) s. Calculate average torque (in Nm) acting on the electron during this transition.

Answer»

`1.055xx10^(-26)`
`4.40xx10^(-27)`
`1.7xx10^(-26)`
`8.79xx10^(-27)`

SOLUTION :`tau=(DELTAL)/(DELTAT)=(L_(2)-L_(1))/(Deltat)`
`=((n_(2)h)/(2pi)-(n_(1)h)/(2pi))/(Deltat)=((n_(2)-n_(1))h)/(2piDeltat)`
`=((3-2)xx6.625xx10^(-34))/(2xx3.14xx1.2xx10^(-8))`
`=8.79xx10^(-27)`
