As we learnt

 

Drift velocity -

 

v_{d}=\frac{-e\vec{E}}{2m}\tau

- wherein

\sigma=\frac{1}{\rho}\rightarrow Relation

J=\frac{I}{A}\rightarrow Relation

E=\frac{V}{l}\rightarrow Relation

\tau\rightarrow Relaxation time

 

 

 

Drift velocity is directly proportional to electric field, relaxation time and inversely proportional to mass of electron.


Option 1)

directly proportional to relaxation time

Option 2)

inversely proportional to electric field

Option 3)

directly proportional to mass of electron

Option 4)

independent of relaxation time.
