The two images you've uploaded show an electrostatics problem with point charges placed on a coordinate system. Let me summarize and analyze the scenario in detail.

Image 1:

• You have charges $q_2 = -5.50 \, \mu C$ fixed at the origin of the coordinate system.
• Another charge $q_1 = 2.50 \, \mu C$ is initially located at point $P$, a distance $d_1 = 5.00 \, \text{cm}$ from the origin along the x-axis.
• Point $R$ is located along the x-axis, at a distance $d_2 = 2.00 \, \text{cm}$ from the origin.
• Additionally, there are charges $q_3$ and $q_4$, each with magnitudes of $2.75 \, \mu C$, half the value of $q_2$, located a distance $a = 1.20 \, \text{cm}$ from the origin along the y-axis.

Image 2:

• The scenario is modified by replacing charge $q_4$ with charge $q_5$, which has the same magnitude $q_5 = 2.75 \, \mu C$ but an opposite sign from $q_4$.

Electrostatics Analysis:

You are likely being asked to calculate the net electrostatic force on one of the charges due to the presence of the others using Coulomb's law:

$F = k_e \frac{|q_1 q_2|}{r^2}$ where $k_e = 8.99 \times 10^9 \, \text{N} \cdot \text{m}^2/\text{C}^2$ is Coulomb's constant, $q_1$ and $q_2$ are the charges, and $r$ is the distance between the charges.

To calculate forces between charges, you’ll need to:

1. Compute the individual forces between the charges on a specific point (e.g., $q_1$ at $P$).
2. Decompose forces into x and y components if necessary.
3. Sum the forces vectorially to find the net force.

Do you need a step-by-step solution for a particular charge, such as calculating the force on $q_1$ at point $P$, or another part of the problem? Let me know how you'd like to proceed!
