Match List - I with List - II:

Figure

Choose the correct answer from the options given below:

Show answer and solution

Answer: (a)

  1. Planck's constant h=E/νh = E/\nu: [ML2T−1][ML^2T^{-1}], so (a) →\rightarrow (ii).
  2. Kinetic energy: [ML2T−2][ML^2T^{-2}], so (b) →\rightarrow (iii).
  3. Electric potential V=W/q=W/(It)V = W/q = W/(It): [ML2I−1T−3][ML^2I^{-1}T^{-3}], so (c) →\rightarrow (iv).
  4. Linear momentum p=mvp = mv: [MLT−1][MLT^{-1}], so (d) →\rightarrow (i).
  5. So the answer is (a).
