Question

A body of mass 5 kg is supported by a light cord. Find the tension on the cord. (g = 10m/s2 )

Answer 1

tension will be 50N if cord is mass less.

Answer 2

Concept: A force that travels down the length of a medium, particularly one conveyed by a flexible medium like a rope or cable, is said to be in tension.

A force pair acting at each end of the aforementioned elements can be referred to as tension. When thinking about a rope, every part of the rope, excluding the ends, experiences tension force in both directions. Along with the force from the attached weight, the terminals experience tension on one side. The tension fluctuates in some situations all along the string.

Ropes cannot effectively push, hence tension is a pulling force rather than a pushing force. Pushing the rope will result in it becoming slack and losing the tension it has. Although it may seem clear, when depicting the forces acting on an item, individuals frequently show the tension force moving in the opposite direction. It is crucial to keep in mind that stress can only draw an object, not push it.

Given: mass of body = 5 kg

           g = 10 $m/s^2$

To find: the tension on the cord

Solution:

the tension on the cord = force on the body

the tension on the cord = m × g

the tension on the cord = 5 kg × 10 $m/s^2$

the tension on the cord = 50 N
