Two persons are pulling the ends of string in such a way that the string is stretched horizontally. When a weight of \[\mathbf{10}\text{ }\mathbf{kg}\] is suspended in the middle of the string, the string does not remain horizontal. Can the persons make it horizontal again by putting it with a greater force?

Answer:

                No, the vertical weight cannot be balanced by the horizontal force, however large the two forces may be.
