Bulk modulus for rubber is `9.8xx10^(8)Nm^(-2)`. To what depth should a rubber ball be taken in a lake so that its volume is decreased by `0.1%`A. `0.1m`B. `1m`C. `10m`D. `100m` |

Answer» Correct Answer - D `B = (Delta P)/((Delta V//V)) rArr Delta P = B xx (Delta V)/(V)` `rArr Delta P = 9.8xx10^(8) xx10^(-3) = 9.8xx10^(5) Nm^(-2)` `Delta P = rho gh` `h = (Delta P)/(rho g) = (9.8xx10^(5))/(10^(3)xx9.8) rArr h = 10^(2) m = 100m` |
