## Homework Statement

Find the magnetic forces acting on each electron in the attached image

## Homework Equations

B = [itex]\frac{μ0}{4pi}[/itex]*q*[itex]\frac{v x \hat{r}}{r^{2}}[/itex]

F[itex]_{m}[/itex] = qv x B

## The Attempt at a Solution

B[itex]_{1}[/itex] = 10[itex]^{-7}[/itex] * 1.6*10[itex]^{-19}[/itex] * [itex]\frac{5000*10^{3}*sin(45)}{(10*10^{-10})(10*10^{-10})}[/itex]

B[itex]_{1}[/itex] = .057

Fm[itex]_{2}[/itex] = (1.6*10[itex]^{-19}[/itex])*1000*10^3*.057

Fm[itex]_{2}[/itex] = 9.12*10^{-15}

Now at this point I know something is wrong, but I'm not sure what. I thought the force on the 2nd electron would be the force created by the 1st electron, but that number is definitely screaming incorrect to me. I figure it I understand how to figure out the force on 1 I can figure out the force on the other. (Electron 1 is at the bottom, electron 2 at the top). Where is my mistake?
