Can you explain the answer of this question below:The dimensional representation of Planck's constantis identical to that ofA:TorqueB:WorkC:StressD:Angular momentumThe answer is d.

Question

Answer

Planck's constant (h)= E/v .. SI unit of planck's constant = joule /s or m^2 kg/s so , dimensional formula of planck's constant = [ML2T-2] ... now angular momentum (I) = r*p   then I =r*p =[L] [MLT-1] = [ML2T-2]........So dimensional representation of planck's constant is identical to angular momentum

Answer

In bohrs model of atom we had nh/2pie=angular momentum as n 2 and pie are dimension less so dimension of h = dimension of angular momentum morever u can equate it by using formula angular momentum = mvr here r is distance it will be same as h i.e planks constant
