### Example Problem: Gravitational Forces in the Sun-Earth-Moon System

#### Problem Description:
The drawing (not to scale) shows one alignment of the sun, earth, and moon. The gravitational force \(\vec{F}_{SM}\) that the sun exerts on the moon is perpendicular to the force \(\vec{F}_{EM}\) that the earth exerts on the moon. The masses are:

- Mass of the sun (\(m_{S}\)) = \(1.99 \times 10^{30}\) kg
- Mass of the earth (\(m_{E}\)) = \(5.98 \times 10^{24}\) kg
- Mass of the moon (\(m_{M}\)) = \(7.35 \times 10^{22}\) kg

The distances shown in the drawing are:

- Distance between the sun and the moon (\(r_{SM}\)) = \(1.50 \times 10^{11}\) m
- Distance between the earth and the moon (\(r_{EM}\)) = \(3.85 \times 10^{8}\) m

Determine the magnitude of the net gravitational force on the moon.

#### Diagram Explanation:
The diagram illustrates the following key points:

- The Sun is represented as a yellow star on the left side of the diagram.
- The Earth is depicted as a blue sphere with green continents at a lower vertical position.
- The Moon is shown as a smaller gray sphere in the upper region of the drawing, located such that it forms a right angle with lines extending from the Earth and the Sun.
- Two forces are acting on the Moon:
  - \(\vec{F}_{SM}\) (blue arrow pointing from the Sun to the Moon) represents the gravitational force exerted by the Sun on the Moon.
  - \(\vec{F}_{EM}\) (blue arrow pointing from the Earth to the Moon) represents the gravitational force exerted by the Earth on the Moon.
  - The distance \(r_{SM}\) is the horizontal distance between the Sun and the Moon.
  - The distance \(r_{EM}\) is the vertical distance between the Earth and the Moon.
