$($a$)$ What is the magnitude $($in $\frac{N}{C})$ of the electric field at a point $2\mathrm{.}00cm$ to the right of $A?$

field vectors? What is the magnitude of the electric field due to a point charge? Add the fields as vectors to get the net field. Be careful with units and signs. N$/$C

$($b$)$ A fourth bead with a charge of $-5\mathrm{.}00nC$ is placed at this point. What are the magnitude $($in $N)$ and direction of the net electric force on it$?$
