The time dependance of a physical quantity P is given by P=P_(0)e^(alphat^(2) where alpha is a constant and t is time. Then constant alpha is :

Answer»

DIMENSIONLESS
has dimension of `T^(-2)`
has dimension of `P`
has dimension of `T^(2).`

SOLUTION :Here `alphat^(2)` is a dimensionless. Therefore, `ALPHA=(1)/(t^(2))` and `alpha` has the dimensions of `T^(2).`
Hence correct CHOICE is `(b).`
