![**Problem Overview: Calculating Net Force Using Coulomb’s Law**
Two charges, +8 μC and +10 μC, are placed along the x-axis. The first charge is at the origin (\(x = 0\)) and the second charge at \(x = +1 \, \text{m}\). Determine the magnitude and direction of the net force on a -3 nC charge when placed at the following locations.
**Steps for Solution:**
1. **Use of Coulomb's Law:**
- Review Section 5.3 Coulomb’s Law.
- Calculate the force due to each of the two charges.
- Sum the forces for the net force, considering directions for accuracy. Part (c) will require a vector sum.
2. **Problem Locations:**
- **a.** Halfway between the two charges:
- Determine the magnitude and select the direction from dropdown options.
- **b.** On the x-axis at \(x = -0.5 \, \text{m}\):
- Determine the magnitude and select the direction from dropdown options.
- **c.** At the coordinate (1 m, 0.5 m):
- This requires considering a direction perpendicular to the line joining the two fixed charges.
**Hints and Calculations for Part (c):**
- This is a 2-dimensional problem.
- The charge at \(x = 1 \, \text{m}\) affects force along the y-direction.
- Charge at the origin affects force along the line joining \((x, y) = (0, 0)\) and \((x, y) = (1 \, \text{m}, 0.5 \, \text{m})\).
- Express each force vector in terms of \(x\) and \(y\) components, sum them, and calculate the resultant magnitude using the Pythagorean theorem.
- Use \(\tan(\theta) = \frac{F_y}{F_x}\) to find direction.
**Answer Submission:**
- Enter the magnitude of force in mN and direction in degrees.
- Use the "Submit Question" option for checking answers.
