Part A

Two point charges are placed on the $x-$axis as

follows: charge $q_1=4\mathrm{.}05nC$ is located at

$x=0\mathrm{.}199m,$ and charge $q_2=5\mathrm{.}05nC$ is at

$x=-0\mathrm{.}302m.$

What is the magnitude of the total force exerted by these two charges on a negative point charge $q_3=-6\mathrm{.}03nC$ that is

placed at the origin?

Express your answer in newtons.
