A certain conductor has 6.50 1028 free electrons per cubic meter, a cross-sectional area of 4.00 10-6 m2, and carries a current of 2.10 A. Find the drift speed of the electrons in the conductor.

I=n A V(drift)
I - current
n - number of free electrons per unit volume in the conductor
A - area of the conductor
V(drift) avg drift speed

V(drift)=I/(n A)
V(d)=2.10 /(6.50 e+28 x 4.00 e-6 )

V(d)=8.07 e-24 m/s
or

V(d)=8.07 10-24 m/s (according to your notation)
