Homework Statement
A wire segment 1.2 m long carries a current I = 3.5 A, and is oriented as shown in the figure. The +x-axis points directly into the page. A uniform magnetic field of magnitude 0.50 T pointing toward the -x direction is present as shown. What is the magnetic force vector on the wire segment?
Homework Equations
Fm=Il x B
l=1.2m
h sin θ
h cos θ
The Attempt at a Solution
1.2 sin 30° = 0.6m
1.2 cos 30°= 1.04m
Fm= I | i j k |
| 0 1.4m 0.6m |
|0.5T 0 0 |
=3.5 (0.3 j + 0.7 k)
= 1.05 j + 2.45 k
so that's my attempt... but is totally wrong, my answer is not near any of the options. Does anyone knows what am I doing wrong??
Thank you!
