The bulk modulus of a spherical object is `B` if it is subjected to uniform pressure `p`, the fractional decrease in radius is:A. `(B)/(3p)`B. `(3p)/(B)`C. `(p)/(3B)`D. `(p)/(B)` |

Answer» `B = - (Delta P)/(Delta V//V)` `(Delta V)/(V) = -(P)/(B)` `V = (4)/(2) pi R^(3)` `(Delta V)/(V) = 3 (Delta R)/(R )` `(Delta R)/(R ) = - (p)/(3B)` |
