Question

A ball falling in a lake of depth 200m shows a decrease of o.1% in its volume at the bottom. The bulk modulus of the ball is

Answer 1

Hey dear,

◆ Answer-
B = 19.6×10^8

◆ Explaination-
# Given-
h = 200 m
∆V/V = 0.1 %

# Solution-
Bulk modulus of material is given by-
Bulk modulus = Pressure / Strain
B = P / (∆V/V)

Here, we know
P = ρgh
∆V/V = 0.1 %

B = ρgh / (∆V/V)
B = 1000×9.8×200 / (0.1/100)
B = 19.6×10^8

Bulk modulus of the ball material is 19.6×10^8.

Hope this helps...
