JEE Main Physics question
Some physical quantities are given in Column I and some possible SI units in which these quantities may be expressed are given in Column II. Match the physical quantities in Column I with the units in Column II. (Some quantities may have more than one correct match.) **[IIT JEE 2007]**
Column I | Column II ---|--- (A) ( universal gravitational constant, mass of earth, mass of sun) | (p) (volt)(coulomb)(metre) (B) ( universal gas constant, absolute temperature, molar mass) | (q) (kilogram)(metre)(second) (C) ( force, charge, magnetic field) | (r) (metre)(second) (D) ( universal gravitational constant, mass of earth, radius of earth) | (s) (farad)(volt)(kilogram)
Solution
From , has dimension , matching both (q) kg·m³·s⁻² and (p) volt·coulomb·metre (since joule, and joule·metre has this same dimension). From , , matching (r); it also matches (s),
