V = u * E.
Hence, u = V/E.

the drift velocity = 5 m/sec.
field gradient = 100 V/m.
so, mobility = drift velocity/field gradient.

Here in this ques, it is clearly mentioned that,
The drift velocity = 5 m/sec,
Field gradient= 100 V/m,
So, mobility = drift velocity/field gradient.

Drift velocity = mobility * field gradient.

Then mobility = 100/5 = 20.

Manu said:   9 years ago
Drift velocity = mobility * field gradient.

It should be 20, But why 0.05?
