Tension In Rope: Box Suspended & Pulled by Force

[Hamza Abbasi]

A box suspended by a rope is pulled to one side by a horizontal force. The tension in the rope increases! Why is it so?

draw a diagram; write down force balance equation; expand it in coordinate frame if needed

Have you solved the force balance equations, as zwierz suggests, and found that the tension increases, or were you told that it increases and you're trying to understand why?

Because for every action if force there is an equal and opposite reaction. Thus this equal reaction must get exerted upon the rope, as it is supporting the object on which the force was exerted. Ergo...more tension on the rope.
