Answer

The magnetic force is $7.2 \times 10^{-21}~N$ and this force is directed into the page.

Work Step by Step

We can find the magnetic force: $F = q~v\times B$ $F = (-8.0\times 10^{-18}~C)(0.30\times 10^{-2}~m/s)(0.30~T)$ $F = -7.2 \times 10^{-21}~N$ By the right hand rule, $v \times B$ would be directed out of the page if the charge was positive. However, the negative charge results in a force directed into the page. The magnetic force is $7.2 \times 10^{-21}~N$ and this force is directed into the page.
