The dimensionalformula of the product of two physical quantities P and Q is ML^(2)T^(-2) . The dimensional formula of P/Q is ML^(0)T^(-2) . Then what are the units of physical quantities P and Q. |

Answer» SOLUTION :Given `PXXQ ` has dimensions `ML^(2)T^(-2)` P/Q has dimensions `ML^(0)T^(-2)` Hence (PQ) `((P)/(Q))=(ML^(2)T^(-2))(ML^(0)T^(-2))` `P^(2)=M^(2)L^(2)T^(-4)"":. P= ML^(-1)T^(-2) = ` FORCE ..... (1) given `(P)/(Q)= M^(1)L^(0)T^(-2),(ML^(1)T^(-2))/(Q)=ML^(0)T^(-2)` `Q=(ML^(1)T^(-2))/(ML^(0)T^(-2))=L` = Displacement .........(2) |
