Coulomb's Law.

Three charged particles are placed at each of three

corners of an equilateral triangle whose sides are of

length $3\mathrm{.}9cm.$ Two of the particles have a negative

charge: $q_1=-6\mathrm{.}9nC$ and $q_2=-13\mathrm{.}8nC.$ The

remaining particle has a positive charge, $q_3=8\mathrm{.}0$

$nC.$ What is the net electric force acting on particle

$3$ due to particle $1$ and particle $2?$

Previous Answers

Correct

You are asked to find the net force acting on particle $3.$ Centering the $xy$ coordinate system on particle $3$ will make this

easier.

EXECUTE the solution as follows

Part B

Find the net force $vec(F{)}_3$ acting on particle $3$ due to the presence of the other two particles. Report you answer as a magnitude

$F_3$ and a direction $$ measured from the positive $x$ axis.

Express the magnitude in newtons and the direction in degrees to three significant figures.
