Q104 / 200 · NEET 2005 · Physics

The ratio of the dimension Planck's constant and that of moment of inertia is the dimension of:

  • A
    time
  • Correct answer
    B
    frequency
  • C
    angular momentum
  • D
    velocity

Solution

$\frac{h}{I}=\frac{\mathrm{E} \lambda}{\mathrm{C} \times \mathrm{I}}=\frac{\left[\mathrm{ML}^2 \mathrm{~T}^{-2}\right][\mathrm{L}]}{\left[\mathrm{LT}^{-1}\right]\left[\mathrm{ML}^2\right]}$ $\frac{h}{I}=\left[\mathrm{T}^{-1}\right]=\text { Frequency }$

Hence, the correct answer is option: 'B'.
