What is Dimensional Formula of Tension?

Tension is defined as the magnitude of force.

Mathematically,

Tension = Force.
Dimensional Formula of Force= M¹L¹T^-2. [Check how Dimensional Formula of force is derived]

Putting these values in above equation we get,

Dimensional Formula of Tension= M¹L¹T^-2
SI unit of Tension is Newton (N).
