JEE Main 2024 — Mechanical Properties of Solids Question with Solution

JEE Main 2024 (31 Jan Shift 1)

Question

The depth below the surface of sea to which a rubber ball be taken so as to decrease its volume by 0.02% is _____ m.

(Take density of sea water =103 kg m-3, Bulk modulus of rubber =9×108 N m-2, and g=10 m s-2)

Correct answer
18

Step-by-step explanation

Bulk modulus is given by, B=-∆P∆VV

⇒∆P=-B∆VV

⇒ρgh=-B∆VV

⇒103×10×h=-9×108×-0.02100

⇒h=18 m
