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/b . 1/x - (t^(2))/(bx)` br>[Pressure]=`[a/b . 1/x]` Also [Pressure]`=[(t^(2))/(b.x)],[ML^(-1)T^(-2)]=[a/b][1/L]:.[a/b]=[MT^(-2)]`
