Question 21 of 118

Match List-I with List-II :
$\begin{array}{|c|c|c|c|}
\hline & \text { List-I } & & \text { List-II } \\
\hline \text { (A) } & \text { A force that restores an elastic body of unit area to its original state } & \text { (I) } & \text { Bulk modulus } \\
\hline \text { (B) } & \text { Two equal and opposite forces parallel to opposite faces } & \text { (II) } & \text { Young's modulus } \\
\hline \text { (C) } & \begin{array}{l}
\text { Forces perpendicular everywhere to the surface per unit area } \\
\text { same everywhere }
\end{array} & \text { (III) } & \text { Stress } \\
\hline \text { (D) } & \text { Two equal and opposite forces perpendicular to opposite faces } & \text { (IV) } & \text { Shear modulus } \\
\hline
\end{array}$
Choose the correct answer from the options given below :

A(A)-(IV), (B)-(II), (C)-(III), (D)-(I)B(A)-(III), (B)-(IV), (C)-(I), (D)-(II)C(A)-(II), (B)-(IV), (C)-(I), (D)-(III)D(A)-(III), (B)-(I), (C)-(II), (D)-(IV)

Show answer and solution▾

Answer: (B) (A)-(III), (B)-(IV), (C)-(I), (D)-(II)

(1) stress $=\frac{F_{\text {restoring }}}{A}$
If $\mathrm{A}=1$
Stress $=F_{\text {restoring }}$
(A)-(III)
(2)
(B)-(IV)
(3)
(C)-(I)
(4)
(D)-(II)
