Two forces F$1$ and F$2$ act on a particle. Force F$1$ acts at an angle $50\backslash$deg clockwise from positive y axis. Force F$2$ acts at an angle $50\backslash$deg counter$-$clockwise from negative y axis. If the magnitudes of the two forces are F$1=600$ N$,$ F$2=900$ N : $($A$)$ Find the magnitude of resultant force and its direction measured counter$-$clockwise from positive x axis, using the Cartesian vector method. $($B$)$ Draw the force and resultant vectors in a diagram.
