A) has no dimension
B) has dimension of \[{{T}^{-2}}\]
C) has dimension of \[{{T}^{2}}\]
D) none of the above
Correct Answer: B
Solution :
We know that the quantity P and \[{{P}_{o}}\] has same dimensions. Also, by theorem of equality the term exp \[(-\alpha {{t}^{2}})\] should be dimensionless. Therefore a has the dimensions of \[{{T}^{-2}}\].You need to login to perform this action.
