As we learnt

 

Drift velocity -

 

Drift velocity is the average velocity that a particle such as an electron attains in a material due to an electric field .        

- wherein

 

 

Drift Velocity = Displacement / time

Displacement = .2 mm = 2×10-4 m

Time = 10 sec

Drift Velocity  Vd = 2×10-5 m/sec

 


Option 1)

2×10-5 m/sec

Option 2)

10-5 m/sec

Option 3)

2×10-4 m/sec

Option 4)
