given, water pressure , P = 2 × 10^7 N/m²

Bulk modulus of water , \beta = 6.1 × 10^10 N/m² .

Volume of solid brass sphere , V = 0.305 m³

Now use formula,

\beta=\frac{P}{\frac{\Delta{V}}{V}} [ didn't include sign ]

6.1 × 10^10 = 2 × 10^7/(∆V/0.305)

∆V = 2 × 10^7 × 0.305/6.1 × 10^10

= 0.610 × 10^7/6.1 × 10^10

= 10^-4 m³

Answer:

given, water pressure , P = 2 × 10^7 N/m²

Bulk modulus of water ,

= 6.1 × 10^10 N/m² .

\beta

Volume of solid brass sphere , V = 0.305 m³

Now use formula,

\beta=\frac{P}{\frac{\Delta{V}}{V}}

[ didn't include sign ]

6.1 × 10^10 = 2 × 10^7/(∆V/0.305)

∆V = 2 × 10^7 × 0.305/6.1 × 10^10

= 0.610 × 10^7/6.1 × 10^10

= 10^-4 m³
