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?

Answer

(a) `[ML^(2)T^(-1)]`, (b) `6.62xx10^(-34) J-s`

Explanation

1 cm `=10^(-2) m`
`1g=10^(-3) kg`
`h=6.62xx10^(-27) (10^(-2) m)^(2) (10^(-3) kg)s^(-1)`
`=6.62xx10^(-34) kg m^(2) s^(-1)`
