A mass M is suspended by a rope from a rigid support at A as shown in figure. Another rope is tied at the end B, and it is pulled horizontally with a force F. If the rope AB makes an angle θ with the vertical in equilibrium, then the tension in the string AB is: Image related to
F sin θ
F/sin θ
F cos θ
F/cos θ

Solution:

Let us see the Free body Diagram of the arrangement

For Equilibrium, T Cos  θ = Mg and T Sin θ = F ;

As, T Sin θ = F ; T= F/ Sinθ
