Question

The unit of Planck's constant h is that of (A) energy (B) work (C) linear momentum (D) angular momentum

Tardigrade Admin · Accepted Answer

Planck constant h=(E/v) Unit of h=( text unit of E/ text unit of v)=( text Joule / text per sec )=J-s Unit of angular momentum J=I ω m r2 ω=k g m2 / sec =J-s Thus, unit of h= unit of J

Q. The unit of Planck's constant $h$ is that of

energy

work

linear momentum

angular momentum

Planck constant $h = \frac{E}{v}$
Unit of $h = \frac{unit of E}{unit of v} = \frac{Joule}{per sec} = J_{- s}$
Unit of angular momentum $J = I ωm r^{2} ω = k g m^{2} / sec = J_{- s}$
Thus, unit of $h =$ unit of $J$
