A physical quantity is measured and its value is found to be nu where n = numerical value and u = unit. Then which of the following relations is true

$n \propto u^{2}$

$n \propto u$

$n \propto \sqrt{u}$

$n \propto \frac{1}{u}$

You've reached today's free limit of 20 questions. Log in to keep practising for free.

Explanation

$P = n u ∴ n \propto \frac{1}{u}$

Explanation

$E = h ν \Rightarrow h = \frac{E}{ν} = j o u l e - s$

● ● ● ● ●

SI unit of permittivity is

$C^{2} m^{2} N^{- 1}$

$C^{- 1} m^{2} N^{- 2}$

$C^{2} m^{2} N^{2}$

$C^{2} m^{- 2} N^{- 1}$

You've reached today's free limit of 20 questions. Log in to keep practising for free.

Explanation

$F = \frac{1}{4 π \in} \frac{q_{1} q_{2}}{r^{2}} \Rightarrow \in = \frac{1}{4 π} \frac{q_{1} q_{2}}{F r^{2}} = C^{2} m^{- 2} N^{- 1}$
