Two rods, one hollow and the other solid, made of the same material have the same length of 20 cm and radius of 2 cm. When their temperature is increased through the same amount of $5 0^{\circ} C$ , their expansion ratio $E_{h} : E_{s}$ will be:

Options:

Answer:

Solution:

For linear expansion, $Δ L = αL Δ T$ . Both rods have the same $α, L$ and $Δ T$ . Hence $Δ L_{h} : Δ L_{s} = 1 : 1$ . \end{document}
