16. Three Forces F₁, F2, and F3 together keep a body in equilibrium. If F₁ = 3 N along the positive X-axis, F₂ = 4N along Equilibrium Of Forces the positive Y-axis,then the third force F3 is (A) 5 N-making an angle = tan-¹(3/4) with negative y-axis (B)5 N-making an angle 0 = tan-¹(4/3) with negative y-axis (C) 7 N-making an angle 0 = tan-1(3/4) with negative y-axis (D) 7 N-making an angle 0 = tan-¹(4/3) with negative y-axis ​
