Question

Which quantity bas a dimension ML2T-2

Answer 1

Answer:

Work or Energy has the dimesion of ML^2 T-2.

Since, the formula for work done is given as

Work (or Energy dimensionally) = Force * Displacement

And , force = mass * acceleration

So,

Mass is dimesion having M

acceleration is metres/sec^2 so, LT^-2

and, Displacement having length L

So, the total dimension of the work becomes when all of these multiplied ML^2T-2.

Hope this helps you !
