Physics And Measurement Question 56

Question: The dimensional formula for Planck’s constant $(h)$ is

[AFMC 2003; RPMT 1999; Kerala PMT 2002]

Options:

A) $M L^{- 2} T^{- 3}$

B) $M L^{2} T^{- 2}$

C) $M L^{2} T^{- 1}$

D) $M L^{- 2} T^{- 2}$

Show Answer

Answer:

Correct Answer: C

Solution:

$E = h v \Rightarrow [M L^{2} T^{- 2}] = [h] [T^{- 1}] \Rightarrow [h] = [M L^{2} T^{- 1}]$
