Question

One of the combinatios from the fundamental physical quantities constants is hc/g. Unit expression

Answer 1

hc = 1239.84 eV nm

and G is the gravitational constant = 6.67×10⁻¹¹ Nm²/Kg²

So, unit of hc/G = eV nm/(Nm²/Kg²)

= eV nm×Kg² /(Nm²)

Here, eV= electronvolt

nm= nano-meter

N=newton

m=meter

Kg= kilogram
