Question

if (A^2/mass)has the dimension of kinetic energy.then A
has the dimension of?

Answer 1

What is the dimension of kinetic energy ?

Answer 2

dim of kinetic energy is ML^2T^-2

Answer 3

So you have \[\frac{[A]^2}{M} = [M][L]^2[T]^{-2}\]
That is \[ [A]^2 = [M]^2[L]^2[T]^{-2}\]
What should be [A] ?

Answer 4

MLT^-1

Answer 5

Correct! That is the dimension of linear momentum..

Answer 6

ya but htere is no option of linear momentum.....

Answer 7
