Final answer:
To find the x-component of the force on a charge located at x = 8 cm, you need additional information about the positions and charges of other charges in the system.
Step-by-step explanation:
The force on a charge located at x = 8 cm in Figure 18.48(a) can be found using the formula F = k * (q1*q2) / r^2, where k is the electrostatic constant, q1 and q2 are the charges, and r is the distance between them.
In this case, we have q = 1.1 μC and we need to find the x-component of the force. Since the charge is located at x = 8 cm, we need to calculate the force between this charge and other charges in the system to find its x-component.
Without additional information, it is not possible to determine the x-component of the force on the charge at x = 8 cm. It depends on the positions and charges of other charges in the system.
