Three fixed charges are arrayed in the shape of a right triangle, as shown below, where a = 4.0 cm, b = 3.0 cm, and c = 5.0 cm. The magnitude of charge q is 3.55 μC, but the sign of the charge is not known (i.e., it could either be positive or negative). The magnitude and sign of q2 are both unknown; the value of q3 is +5.05 μC. The net force F on q3 is entirely in the negative x-direction. Calculate the magnitude of q2.

Question
Three fixed charges are arrayed in the shape of a right triangle, as shown below, where a = 4.0 cm, b = 3.0 cm, and c = 5.0 cm. The magnitude of charge q is 3.55 μC, but the sign of the charge is not known (i.e., it could either be positive or negative). The magnitude and sign of q2 are both unknown; the value of q3 is +5.05 μC. The net force F on q3 is entirely in the negative x-direction. Calculate the magnitude of q2.
The image depicts a triangular arrangement of three point charges labeled \( q_1 \), \( q_2 \), and \( q_3 \). The sides of the triangle are labeled \( a \), \( b \), and \( c \). The angle between the sides containing charges \( q_3 \) is marked with a right-angle symbol.

Attributes of the Diagram:

- **Charges**: 
  - \( q_1 \) and \( q_2 \) are placed at the lower vertices of the triangle, connected by side \( c \).
  - \( q_3 \) is placed at the vertex opposite side \( c \).

- **Forces and Directions**:
  - A force labeled \( \mathbf{F} \) is depicted as an arrow pointing leftward, originating from \( q_3 \).

- **Axes**: 
  - The \( x \) and \( y \) axes are shown to the left of \( q_1 \), indicating directionality with \( x \) pointing right and \( y \) pointing upwards.

This configuration can be used to analyze the vector nature of electric forces in a system of point charges and explore concepts such as equilibrium, net force, and electric field interactions.
