A pressure of 7x10^5N/m is applied to all surfaces of a copper cube (of sides 25 cm) what is the fractional change in volume of a cube? ( for copper B= 14x10^10N/m)

The correct solution is " %".

Explanation:

The given values are:

Pressure,

for copper,

As we know,

The Bulk Modulus (B) =

or,

The decrease in volume will be:

=

then,

=

On putting the values, we get

=

=
