If the string is not fixed and doesn't move because of friction, then the tension in the string at a distance x from the end at which force applied is T=F(L−x)/L,
Answer:(c) F(L−x)/L
If the table is frictionless and the another end of thestring is fixed, then each point of the string has the same tension T = F.
