As I sketch the triangle in my mind, I see Theta=arctan mg/12 where theta is the angle with the horizontal
but mg/Tension=sinTheta
so tension=me/sinTheta where theta is arctan mg/12
A flag of mass 2.5 kg is supported by a single rope as show in figure 13. a strong horizontal wind exerts a force of 12 N on the flag. Calculate the tension in the rope and the angel, the rope makes with the horizontal.
here is the figure:
