Transcribed Image Text:**Problem 2:**
**Statement:**
Three charges are arranged at the corners of an equilateral triangle, as shown in the figure below. Point A is at the center of the triangle and Point B is midway between the two negative charges. (*Note: The angles of an equilateral triangle are 60°.*)
**Figure:**
The figure depicts an equilateral triangle, each side measuring 3.0 cm. The charges are placed at each corner of the triangle:
- The top vertex has a charge of +1.0 nC.
- The bottom left vertex has a charge of -2.0 nC.
- The bottom right vertex has a charge of -2.0 nC.
Point A is marked at the geometric center of the triangle, while Point B is located at the midpoint between the two negative charges along the base of the triangle.
