What are dimensions of Planck's constant. What other physical quantity has the same dimensions ? |
| Answer» Solution :DIMENSIONS of PLANCK's constant, `H = kg m^(2) s^(-1)` Angular MOMENTUM `= mvr = kg (m s^(-1)) m = kg m^(2) s^(-1)` has the same dimensions (Remember from Bohr's POSTULATE, `mvr = n (h)/(2pi)`) | |
