If the relative density of gold is 19.3 and the density of water is 10° g/m°, what will be the density of gold in SI units? | UPSC CAPF 2026 Q No 113

Accepted Answer: (B) 19300 kg/m?

Topic Covered: Physics

Key Concept: Mechanics, electricity, waves and thermodynamics

Relative density is the ratio of the substance density to water density. Convert 10^6 g/m³ to 10^3 kg/m³, then multiply by 19.3.

The key is to apply the central fact, formula, definition or relationship tested in the question and then eliminate alternatives that do not satisfy it.
