Problem

A proton moves horizontally to the right at a speed of

1.0\times10^{5}\,\text{m/s}

through a region containing a uniform electric field of

3.0\times10^{3}\,\text{V/m}

directed upward and a uniform magnetic field of

0.020\,\text{T}

directed out of the page. What is the magnitude of the net force acting on the proton? a)

8.0\times10^{-16}\,\text{N}

5.8\times10^{-16}\,\text{N}

1.6\times10^{-16}\,\text{N}

4.8\times10^{-16}\,\text{N}
