PhysicsEasysingle choice

$A$ and $B$ are two wires. The radius of $A$ is twice that of $B$ . They are stretched by the same load. Then the stress on B is

Options:

Answer:

Solution:

Stress $= \frac{Force}{Area} ∴$ Stress $\propto \frac{1}{π r ^{2}}$ $\frac{S _{B}}{S _{A}} = (\frac{r _{A}}{r _{B}})^{2} = (2)^{2} \Rightarrow S_{B} = 4 S_{A}$
