MCQ
Planck constant has the same dimensions as:
  • A
    Force $\times $ time.
  • B
    Force $\times $ distance.
  • C
    Force $\times $ speed.
  • ✓
    Force $\times $ distance $\times $ time.
✓

Answer

Correct option: D.
Force $\times $ distance $\times $ time.

Planck's constant
$\text{h}=\frac{\text{E}}{\text{v}}=\frac{\text{Force}\times\text{distanace}}{\text{frequency}}$
$\Rightarrow\text{h}=\text{force}\times\text{distance}\times{\text{times}}.$
