The dimensionla formula for the product of two physical quantities `P` and `Q` is `[ML^(2) T^(-2)]`. The dimensional formula of `(P)/(Q)` is `[MT^(-2)]`. Then `P` and `Q` respectively areA. Force and velocityB. Momentum and displacementC. Force and displacementD. Work and velocity |

Answer» Correct Answer - C `PQ = ML^(2) T^(-2)`....(1), `(P)/(Q) = MT^(-2)` ....(2) `(1)xx(2) = p^(2) = M^(2) L^(2) T^(-4)` `implies P = MLT^(-2)` = Force `(1)//(2) = Q^(2) = L^(2)` |
