Hello friends, I have heard that when we suspend a body of mass m with the help of a string, there happens to be another force called tension applied by the string upwards. Why is there tension in the first place? Does it depend on gravitational force?(weight of the body?). Does Tension arise due to the weight of the body and if there was no weight for the object,will there be any tension? It is possible for you people to help me understand the concept of tension by giving some similar example but too different? i mean Tension in the form of another way?
