Question

Physics Headache™2 : 20 Points , 5 Minutes , Question 8

Answer 1

using principle of homogeinity
we found that dimension of alpha is T^-2
because p and p° have same dimensions so e will be dimensionless for this option
B is correct.

Answer 2

We know that 
p and p° have same dimensions which tells that e will also be dimension less by principle of homogeinity .

So by solving the equation by taking log both side we can say that
                                           α = $T^{-2}$

so option b) is correct.
