AP EAMCET · PHYSICS · Units and Dimensions
A certain physical quantity is calculated from the formula \(\frac{\pi}{3}\left(a^2-b^2\right) h d\), where \(a, b\) and \(h\) are all lengths and \(d\) is density. The physical quantity being calculated is
- A velocity
- B volume
- C mass
- D acceleration
Answer & Solution
Correct Answer
(C) mass
Step-by-step Solution
Detailed explanation
\(\frac{\pi}{3}\left(a^2-b^2\right)\) hd ...(1) a, b, h has length "l" so there unit is \(\mathrm{m}(\mathrm{L})\) \(\mathrm{d}=\) density \(=\frac{\text { Mass }}{\text { volume }}=\frac{\mathrm{kg}}{\mathrm{m}^3}=\frac{\mathrm{M}}{\mathrm{L}^3}\) \(\frac{\pi}{3}\) has no…
