Your answer is partially correct.

Three charges are fixed to an $xy$ coordinate system. A charge of $+22C$ is on the $y$ axis at $y=+3\mathrm{.}7m.$ A charge of $-13C$ is at the origin.

Lastly, a charge of $+49C$ is on the $x$ axis at $x=+3\mathrm{.}7m.$ Determine $($a$)$ the magnitude and $($b$)$ direction of the net electrostatic force on

the charge at $x=+3\mathrm{.}7m.$ Specify the direction as a positive angle relative to the $+x$ axis.
