Find the dimensions of Planck's constant...

Find the dimensions of Planck's constant. If its value in cgs system is `6.62xx10^(-27)` erg - sec, what will be its value on mks system?

Text Solution

Verified by Experts

`h =(E )/(v) = ([MLL^2T^(-2)])/([T^(-1)]) = [M^1 L^2 T^(-1)]`
`h = 6.62xx10^(-27) erg -sec.`
`= 6.62xx10^(-27)xx10^(-7) joule sec`
`=6.62xx10^(-34)Js`
