Question

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 units then 

Options

• n ∝ size of u

• n ∝  u²

• n ∝ `sqrt (u)`

• n ∝ `1/u`

Answer 1

n ∝ `1/u`
The larger the unit used to express the physical quantity, the lesser will be the numerical value.
