1. The problem statement, all variables and given/known data "A particle of mass m moves in a circle of radius R. Using dimensional argument, determine the particle angular momentum." 2. Relevant equations L = mvr 3. The attempt at a solution Because L = mvr, the dimensionality would be ML2T-1. I don't know where to go from here so if someone could point me in the right direction it'd be appreciated. Thanks!
