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 are

Options

A. Force and velocity
B. Momentum and displacement
C. Force and displacement
D. work and velocity

Answer

C

Explanation

`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`
