Question
**Homework 2:**

A 35 cm diameter solid sphere \((\rho = 4500 \, \text{kg/m}^3)\) is suspended by a cable as shown below. Half of the sphere is in one fluid \((\rho = 1200 \, \text{kg/m}^3)\) and the other half is in another \((\rho = 1500 \, \text{kg/m}^3)\). 

What is the tension in the cable?

---

**Diagram Explanation:**

The diagram illustrates a solid sphere partially submerged in two different fluids. The sphere is held by a cable from above. 

- The diameter of the sphere is indicated as 35 cm.
- The top half of the sphere is submerged in a fluid with a density of 1200 kg/m\(^3\).
- The bottom half of the sphere is submerged in a fluid with a density of 1500 kg/m\(^3\).
- The total height of submersion is labeled as 120 cm.

This setup is used to determine the tension in the cable supporting the sphere.

Expert Solution
Step 1: Write the given data with suitable variables-

D equals 35 space c m
rho subscript s equals 4500 space kg divided by straight m cubed
rho subscript 1 equals 1200 space kg divided by straight m cubed
straight rho subscript 2 equals 1500 space kg divided by straight m cubed
V subscript 1 equals Volume space of space body space immersed space in space liquid space 1
V subscript 2 equals Volume space of space body space immersed space in space liquid space 2
V subscript s equals space 4 over 3 pi R cubed equals space 4 over 3 pi open parentheses fraction numerator 0.35 over denominator 2 end fraction close parentheses cubed equals 0.022449 space straight m cubed
