An electron that has a velocity with $x$ compment $2\mathrm{.}9{10}^6\frac{m}{s}$ and $y$ component $3\mathrm{.}1{10}^6\frac{m}{s}$ moves through a uniform magnetic field with $x$ component $0\mathrm{.}032$ T and $y$ component $-0\mathrm{.}15$ T $.($a$)$ Find $z$ component of the magnetic force on the electron. $($b$)$ Repeat your calculation for a proton having the same velocity.
