The dimensions of `a/b` in the equation `P=(a-t^(2))/(bx)` where `P` is pressure, `x` is distance and `t` is time are

Options

A. `MT^(-2)`
B. `M^2 LT^(-3)`
C. `ML^3 T^(-1)`
D. `LT^(-3)`

Answer

A

Explanation

`P = (a-t^2)/(bx)`
`[a] = [T^2]`
`[T^2/(bx)]=[(a)/(bx)]=[P]implies[a/b]=[ML^(-1)T^(-2)L]`
