Drift velocity in a metallic conductor: ...

Drift velocity in a metallic conductor:
At room temperature there are large number of free electrons having zero average velocity, but when electric field is applied, the free electrons start moving in a direction opposite to the direction of the applied field with a velocity called drift velocity.

The magnitude of drift velocity is

A

`(eE)/(m_eiota)`

B

`(Ee_iota)/m_e`

C

`(m_eiota)/(eE)`

D

`m_e/(eEiota)`
