Bohr Model: Orbits, Speed & Angular Momentum

Given below are two statements:

Statement (I): The dimensions of Planck's constant and angular momentum are same. Statement (II): In Bohr's model electron revolve around the nucleus only in those orbits for which angular momentum is integral multiple of Planck's constant.

In the light of the above statements, choose the most appropriate answer from the options given below:

Show answer and solution

Answer: (b)

Statement I: $[h] = [E/f] =$ J s $= [ML^2T^{-1}] = [L]$ . True.
Statement II: Bohr's condition is $L = n\dfrac{h}{2\pi}$ , an integral multiple of $\dfrac{h}{2\pi}$ , not of $h$ . False.
So the answer is (b).
