The average depth of indian ocean is about 3000 m. The fractional compression, `(DeltaV)/(V)` of water at the bottom of the ocean is
(Given: Bulk moculus of the water `= 2.2 xx 10^(9) N m^(-2) and g= 10 m s^(-2)`)

Text Solution

Verified by Experts

The pressure exerted by a 3000 m column of water on the bottom layer
` p= h rho g = 3000 m xx 1000 kg m^(-3) xx 10 ms^(-2)`
` = 3 xx 10^7 Nm^(-2)`
Fractional compression `Delta V// V, ` is
`Delta V//V ` =stress / B ` = (3 xx 10^7) // (2.2 xx 10^9)`
`= 1.39 xx 10^(-2)` or 1.36%
