### Problem Statement

Two uniform spheres are positioned as shown. Determine the gravitational force \( F \) which the titanium sphere exerts on the copper sphere. The value of \( R \) is 40 mm.

Assume \( a = 5.0 \), \( b = 2.7 \), \( \theta = 38^\circ \).

![Diagram](image-link)

**Description of Diagram:**
The diagram depicts two spheres: one labeled "Titanium" with radius \( R \) and the other labeled "Copper" with radius \( bR \). Both spheres are positioned such that their centers form an angle \( \theta \) with the horizontal axis \( x \) and the vertical axis \( y \). The distance between the center of the titanium sphere and the copper sphere is represented as \( aR \).

### Part 1

#### Question:
Calculate the mass of each sphere.

Assume \( a = 5.0 \), \( b = 2.7 \), \( \theta = 38^\circ \).

**Description of Diagram:**
The second diagram is identical to the first, showing the same two spheres with the same labels, distances, and angles.

#### Answers:
**Titanium Sphere**
\[ m_t = \text{[input box]} \, \text{kg} \]

---

*Note: The diagram is critical for visualizing the relative positions and distances between the spheres, which are essential for calculating the gravitational force and the masses.*
