## Homework Statement

The magnetic force acting on a wire that is

perpendicular to a 5.3 T uniform magnetic

field is 6.5 N.

If the current in the wire is 5.0 A, what

is the length of the wire that is inside the

magnetic field?

Answer in units of m.

## Homework Equations

F = B . I . L

## The Attempt at a Solution

L = F / B . I = 6.5 / 5.3 . 5 = 0.25 m

this is what I did, but the hw system says its wrong.
