Question

How does gravity affect the force of tension

i need a brief answer that explains everything asked
its urgent pls respond asap

Answer 1

According to the Newton's 3rd Law of Motion, "every action has an equal but opposite reaction"

Due to this, whenever there's a mass hanging on a string, it is pulled down by the gravity/weight. Now as we know that weight is a force and an action, therefore an opposite reaction is also produced to that weight which we call the tension in the string. Thus, if we increase the gravity, the tension in the string would automatically increase in order to keep the net force zero newton(N) and to keep the mass in an equilibrium postion

Hope that helps...
