NEETPhysicsUnits and Dimensions
Statement-I: Specific gravity of a fluid is a dimensionless quantity. Statement-II: It is the ratio of density of fluid to the density of water.
Options
- ABoth Statement-I and Statement-II are correct.
- BBoth Statement-I and Statement-II are incorrect.
- CStatement-I is correct & Statement-II is incorrect.
- DStatement-I is incorrect & Statement-II is correct.
Correct answer
A. Both Statement-I and Statement-II are correct.
Step-by-step solution
The specific gravity or relative density is defined as the ratio of the density of the substance to the density of water at (4^ C ). Since specific gravity is a pure ratio, it has no unit and hence, no dimensions.
