How is the tension equal in both sides of the string, if the string is over a pulley with two different masses attached to its sides?

The assumption is:sumanprakasam said:i want to know whether it is an assumption or not

Tension is the force applied to a string that causes it to stretch or be pulled taut. It is measured in units of force, such as newtons or pounds.
According to Newton's Third Law of Motion, for every action, there is an equal and opposite reaction. This means that the force applied to one end of a string will be exerted back on the other end, resulting in equal tension on both sides.
The amount of tension in a string determines how it will behave. Higher tension will result in a string that is stiffer and produces higher-pitched sounds, while lower tension will make the string more flexible and produce lower-pitched sounds.
In most cases, yes. However, there are some factors that can affect tension, such as the elasticity and thickness of the string, as well as external forces acting on the string. These can cause slight variations in tension on each side of the string.
Tension can be adjusted by changing the force applied to the string or by altering the length or thickness of the string. For example, tightening the tuning pegs on a guitar will increase the tension in the strings, resulting in higher-pitched sounds.
