# A sphere of mass \( M \) and volume \( V \) is suspended from a spring scale and completely submerged in a fluid of density \( \rho_f \). What is the reading on the spring scale?

A sphere of mass \( M \) and volume \( V \) is suspended from a spring scale and completely submerged in a fluid of density \( \rho_f \). What is the reading on the spring scale?

- **A.** \[ M g \left( 1 – \frac{ \rho_{\text{obj}} }{ \rho_f } \right) \]
- **B.** \[ M g + \rho_f V g \]
- **C.** \[ \rho_f V g \]
- **D.** \[ M g – \rho_f V g \]
