Write the dimensions of `a//b` in the relation `P = ( a - t^(2))/( bx)` , where `P` is the pressure , `x` is the distance , and `t` is the time .A. `[M^(2)LT^(-3)]`B. `[MT^(-2)]`C. `[LT^(-3)]`D. `[ML^(3)T^(-1)]`

Answer» Correct Answer - b
`(a - t^(2))/(b) = P x rArr [(a - t^(2))/(b)] = [Px]`
`rArr [(a)/(b)] = [Px] = ml^(-1)T^(-2)L = Ml^(-2)`
