Lorentz forceA long straight wire lies along the $x$-axis of a coordinate system. A current of 31 mA flows in the positive $x$-direction through this wire. An electron passes over the wire. The electron has a velocity of, $\large \vec{v}= 371\hat{x}-712\hat{y}$ [m/s]. when it is at a position, $\large \vec{r}= 0\hat{x}+0\hat{y}+0.01\hat{z}$ [m]. What is the Lorentz force from the magnetic field on the electron? $\vec{F}=$ $\hat{x} +$ $\hat{y} +$ $\hat{z}$ [N] |
