1 Physical world and measurement
If the frequency (F), velocity (V) and density (D) are taken as fundamental quantities then the dimensional formula for momentum in this new system will be 1) D-1V-4F3 2) D1V4F-3 3) D1V1F-2 4) D2V2F2
Solution
F = T-1 V = L1T-1 L = VF-1 D = M1L-3 M = D1 L3 Momentum = M1L1T-1 Momentum = [D1 (VF-1)3][ VF-1] [F] Momentum = D1V4F-3
