दिया है -
घन की प्रत्येक भुजा (l) = 10 सेमी = 1.0 मीटर
जलीय दाब (p) = `7 xx 10^(6)` Pa
तब का प्रत्यास्थता गुणांक :
(K) = ` 140 xx 10^(9)` Pa
आयतन में संकुचन `(DeltaV)= ?`
घन का आयतन (V) `= l^(3)`
` = (0.1)^(3) = 1 xx 10^(-3) "मीटर"^(3)`
ताम्बे का प्रत्यास्थता गुणांक (K) = `p/(DeltaV//V) = (pV)/(DeltaV)`
या ` Delta V = (pV)/K`
` Delta V = (7 xx 10^(6) xx 1 xx 10^(-3))/(140 xx 10^(9))`
` = 1/20 xx 10^(-6) "मीटर"^(3)`
` = 0.05 xx 10^(-6) "मीटर"^(3)`
` = 5 xx 10^(-8) "मीटर"^(3)`
