Let $x=\pi R\left(\frac{p^{2}-Q^{2}}{2}\right)$, where $P, Q$ and $R$ are lengths. The physical quantity ' $x^{\prime}$ is
  1. volume
  2. Area Under Curves
  3. velocity
  4. length

Solution

Let \(x=\pi R\left(\frac{P^2-Q^2}{2}\right)\), where \(P, Q\) and Rare lengths. The physical quantity \(x\) is volume. Explanation: Given, \(x=\pi R\left(\frac{\mathrm{p}^2-\mathrm{Q}^2}{2}\right)\) where, P, Q and Rare lengths. So, units of P, Q and Rare meter. \(\therefore\) Unit of \(\mathrm{x}=\mathrm{m}^3\) Which is unit of volume.
