(d) n ∝ 1/u
The larger the unit used to express the physical quantity, the lesser will be the numerical value.
Example:
1 kg of sugar can be expressed as 1000 g or 10000 mg of sugar.
Here, g (gram) is the larger quantity as compared to mg (milligram), but the numerical value used with gram is lesser than the numerical value used with milligram.
