Elastic Modulie

Question

With regard to dependence of quantities given in Columns I and II, match the following columns and choose the correct option from the codes given below.
Column I
(A) Young's modulus of a substance
(B) Bulk modulus of a substance
(C) Modulus of rigidity of a substance
(D) Volume of a substance
Column II
(p) depends on temperature
(q) depends on length
(r) depends on area of cross-section
(s) depends on the nature of material

Solution

Modulus of elasticity (Y, B, $η$ ) depends on the temperature and nature of material. Volume of a substance depends on temperature, length and area of cross-section.
$Hence, A \to p, s; B \to p, s; C \to p, s; D \to p, q, r$
