A solid block of silver with density

10.5 \times {10^3}\,\,\mathrm{kg }{\mathrm{m}^{ - 3}}

is subjected to an external pressure of

{10^7}\,\mathrm{N}{\mathrm{m}^{ - 2}}

. If the bulk modulus of silver is

17 \times {10^{10}}\,\mathrm{N}{\mathrm{m}^{ - 2}}

, the change in density of silver ( in kg

{\mathrm{m}^{ - 3}})

View answer and explanation

Correct option: A

\mathrm{0}\mathrm{.61}

Option A (0.61) is correct because it is the change in density calculated using the bulk modulus formula and the given pressure.
