A sphere or radius 3 cm is subjected to a pressure of 100 atm. Its volume decreases by 0.3 cc. What will be its bulk modulus?A. `4 pi xx 10^(5) atm`B. `4 pi xx 3 xx 10^(3) atm`C. `4 pi xx 10^(6) atm`D. `4 pi xx 10^(8) atm`

Answer» Correct Answer - b
Given, `r = 3cm, Delta V = 0.3 cc`
Bulk modulus, `B = 0 (pV)/(Delta V) = (100 xx (4)/(3) pi r^(3))/(0.3)`
`= 4 pi xx 3 xx 10^(3) atm`
