Three forces F1,F2 and F3 together keep a body is equilibrium. If F1=3N along the positive X-axis F2=4N along the positive Y-axis, then the third force F2 is: F2 and F3 together keep a body is equilibrium. If F1=3N along the positive X-axis F2=4N along the positive Y-axis then the third force F2 is: Three [...]
