Why is tension in a massless string same throughout its length?

Tension in a massless string refers to the pulling force that is exerted on the string in order to keep it taut. It is a measure of the strength of the string and is typically measured in units of Newtons (N).
While a massless string does not have any physical mass, it is still capable of transmitting tension because it is made up of particles that are connected and can transfer forces. This means that tension can still be applied to a massless string and it will behave as expected.
The tension in a massless string is affected by the amount of force applied to the string, the length of the string, and the angle at which the string is pulled. The tension will increase as the force applied increases, and will decrease as the length of the string or the angle of pull increases.
Tension is an important factor to consider in a massless string because it affects the overall stability and behavior of the string. If the tension is too high, the string may break or become unstable, while if the tension is too low, the string may become loose and not function as intended.
In theory, the tension in a massless string can be eliminated if there is no external force acting on the string. However, in practical situations, there will always be some amount of tension present due to the weight of the string itself or other external forces such as gravity.
