Chapter 28, Problem 006
A proton moves through a uniform magnetic field given by
$\vec{B} = (12.3\hat{i} - 18.6\hat{j} + 22.9\hat{k})$ mT. At time $t_1$, the proton has a velocity given by
$\vec{v} = v_x\hat{i} + v_y\hat{j} + (1.63 \text{ km/s})\hat{k}$ and the magnetic force on the proton is $\vec{F}_B = (4.35 \times 10^{-17} \text{ N})\hat{i} + (2.87 \times 10^{-17} \text{ N})\hat{j}$. (a) At
that instant, what is $v_x$? (b) At that instant, what is $v_y$?
