Hello Students, This video contain solution of objective I of HC verma book of page number 9br 1. Which of the following sets cannot enter into the list of fundamental quantities in any system of units ? br (a) length, mass and velocity, br (b) length, time and velocity, br (c) mass, time and velocity, br (d) length, time and mass. br br 2. A physical quantity is measured and the result is expressed as nu where u is the unit used and n is the numerical value. If the result is expressed in various br units then br units then br br 3. Suppose a quantity x can be dimensionally represented in terms of M, L and T, that is, [x] = br m a Lb br — c. The br quantity mass br (a) can always be dimensionally represented in terms of L, T and x, br (b) can never be dimensoinally represented in terms of L, T and x, br (c) may be represented in terms of L, T and x if a = 0, (d) may be represented in terms of L, T and x if a 0. br br 4. A dimensionless quantity br (a) never has a unit, (b) always has a unit, br (c) may have a unit, (d) does not exist. br br 5. A unitless quantity br (a) never has a nonzero dimension, br (b) always has a nonzero dimension, br (c) may have a nonzero dimension, br (d) does not exist.br br br If you have any suggestions,questions then please write in the comment section below..
