got it!
Alright, the only thing that was confusing me was the units for momentum and trying to set as one variable...
What i found was B = mv/rq where mv was the momentum that they gave us. After that it was just plugging in the numbers.
I got my final answer to be 1.5 T
A 2.0 m long wire carries a current of 8.2 A and is immersed within a uniform magnetic field B.
When this wire lies along the +x axis, a magnetic force F= (-2.2 j)N acts on the wire, and when it lies on the +y axis, the force is F = (2.2 i -4.2k)N.
I saw through inspection that B in the y...
Protons with momentum 2.2×10−16 kg*m/s are magnetically steered clockwise in a circular path 1.8 km in diameter at Fermi National Accelerator Laboratory in Illinois.
I am asked to find the magnitude and direction of the field in the magnets surrounding the beam pipe...
I'm fairly certain...
