    Q.1. Write all fundamental physical quantities with their S.I. unit.

    Q.2. Give three examples of such physical quantities which are fundamental in S.I but derived in CGS system.

    Q.3. Let a new system of unit in which mass is defined in unit ‘La’ and length is defined in unit ‘To’ 5 unit of mass in S.I. system is equal to 3 unit of mass in new system & 10 unit of length in S.I. is equal to 5 unit of length in new system of unit. Then find the density of water (= 1000 Kg/m3) in new system of unit.

    Q.4. Define supplementary physical quantity.

    Q.5. Convert 15 unit of acceleration in SI system to  CGS system.
