# Force on a Proton Near Current Carrying Wires

APPHEM-WFMGEM

A proton of charge $\mathit{e}$ moving at speed $\mathit{v_0}$ is placed midway between two parallel wires a distance $\mathit{a}$ apart, each carrying current $\mathit{I}$ in opposite directions.

The force on the proton is:

A

0

B

$\mathit{ev_0\frac{\mu_{0}I}{2{\pi} a}}$

C

$\mathit{ev_0 \frac{\mu_0I}{{2\pi (2a)}}}$

D

$\mathit{ev_0 \frac{\mu_{0}I}{2{\pi}\frac{a}{2}}}$

E

Unable to be determined
