Question

A string is stretched by two equal and opposite forces of 10N each. the tension in the string is???

Answer 1

Hey mate.!!
Tension in the string will be 10N

How?

The string is in equilibrium(a=0)because it is pulled by two equal forces of 10N.

That means any part of the string is also in equilibrium (the string is taut, hence acting like rigid body with again a=0)

Hope it helps you and do mark as brainliest..

Answer 2

If there are no bends in the string, as occur with vibrations or pulleys, then tension is a constant along the string, equal to the magnitude of the forces applied by the ends of the string. By Newton's third law, these are the same forces exerted on the ends of the string by the objects to which the ends are attached.

Tension in the string will be 10N

How?

The string is in equilibrium(a=0)because it is pulled by two equal forces of 10N.

That means any part of the string is also in equilibrium (the string is taut, hence acting like rigid body with again a=0)
