## Homework Statement

A thin metal film of length 1.00 cm, width of 0.250 cm, and thickness of 29.0 micrometers is used to measure the Hall effect. A current of 2.60 A is maintained along the length of the sample. The Hall voltage of 16.0 microVolts is detected across its width, when a magnetic field of 2.00 Tesla is applied normal to the film.

Calculate the drift velocity of the charge carriers.

## Homework Equations

V

_{h}= IB/ned

I=neAV

_{d}

V

_{h}= Hall Voltage

V

_{d}= Drift Velocity

I = Current

B = Magnetic Field

n = Number of electrons

e = Charge of particle

A = area

d = Thickness of film

## The Attempt at a Solution

Using equation 1 I got n = IB/V

_{h}ed

Then I plugged that into equation 2 and solved for V

_{d}but this answer is incorrect.

Any help would be greatly appreciated! Thanks
