Highly selective Backlog Qs for JEE MainPhysicsUnits and Dimensions
Which of the following is the unit of mobility of a electron in a conductor?
Options
- Akg ⁻¹ ~s ^2 ~A ⁻¹
- Bkg ⁻¹ ~s ^2 ~A
- Ckg ⁻¹ ~ms ^2 ~A ⁻¹
- Dkg ms ⁻¹ ~A ⁻¹
Correct answer
B. kg ⁻¹ ~s ^2 ~A
Step-by-step solution
Mobility is given as = e m So, unit of is coulomb - sec kg i.e. kg ⁻¹ ~s ^2 ~A
