A solid brass sphere is subjected to a pressure of 1.0 × 105 Pa due to the earth’s atmosphere. On Venus, the pressure due to the atmosphere is 9.0 × 106 Pa. By what fraction ∆ r/r0 (including the algebraic sign) does the radius of the sphere change when it is exposed to the Venusian atmosphere. Assume that the change in radius is very small relative to the initial radius.
