A $-4\mathrm{.}00$ nCnC point charge is at the origin, and a second $-5\mathrm{.}00$ nCnC point charge is on the xx$-$axis at xx $=0\mathrm{.}800$ mm$.$

Find the electric field $($magnitude and direction$)$ at point on the xx$-$axis at xx $=0\mathrm{.}200$ mm$.$

Find the net electric force that the two charges would exert on an electron placed at point on the xx$-$axis at xx $=0\mathrm{.}200$ mm$.$

Express your answer with the appropriate units. Enter positive value if the force is in the positive xx$-$direction and negative value if the force is in the negative xx$-$direction.
