MCQ
$M{L^{ - 1}}{T^{ - 2}}$ represents
- AStress
- BYoung's Modulus
- CPressure
- ✓All the above three quantities
✓
Answer
Correct option: D.
All the above three quantities
d
Here stress $=f / A$
Here stress $=f / A$
Pressure $=f / A$
So, $[$ stress $]=[$ Pressuue $]=\left[M L^{-1} T^{-2}\right]$
Hiso, $Y=\frac{\text { stress }}{\text { strain }}$ (strain is dimensionliss)
$\therefore Y=f / A=\left[M L^{-1} T^{-2}\right]$
$\therefore$ All the there has seme dimenion equals $\left[ HL ^{-1} T^{-2}\right]$
