The figure below shows three charged particles, all lying along the horizontal axis. Particle A$,$ at left, has a $5\mathrm{.}20$ nC charge. Particle B has a $1\mathrm{.}70$ nC charge and is $3\mathrm{.}00$ cm to the right of A$.$ Particle C has a

$2\mathrm{.}80$ nC

charge and is $2\mathrm{.}00$ cm to the right of B$.$

Find the magnitude $($in N$)$ and direction of the net electric force on each of the particles.
