Question:medium
Two uniform brass rods A and B of length 'l' and '2l' and their radii '2r' and 'r' respectively are heated to same temperature. The ratio of the increase in the volume of rod A to that of rod B is
Two uniform brass rods A and B of length 'l' and '2l' and their radii '2r' and 'r' respectively are heated to same temperature. The ratio of the increase in the volume of rod A to that of rod B is
Show Hint
Logic Tip: Increasing the radius has a greater impact on volume than increasing the length because the radius is squared in the volume formula.

- Each of three blocks \( P \), \( Q \), and \( R \) shown in the figure has a mass of 3 kg. Each of the wires \( A \) and \( B \) has a cross-sectional area of 0.005 cm\(^2\) and Young's modulus \( 2 \times 10^{11} \, \text{N} \, \text{m}^{-2} \). Neglecting friction, the longitudinal strain on wire \( B \) is \( \ldots \times 10^{-4} \). (Take \( g = 10 \, \text{m/s}^2 \))
