Question

[L²M¹T‐²] is the dimensional formula for

Answer 1

Answer:

Couple acting on a body.

Explanation:

It is also known as Torque.

It is expressed as the product of angular acceleration and Moment of inertia..

Moment of Inertia = $M^1L^2T^0$

Dimensions of angular acceleration = $M^0L^0T^-2$

Thus, the dimensional formula of a Couple acting on a body is $L^2 M T^-2$.
