Calculate the magnitude and direction of the force experienced by each charge. **Diagram Description:** * **Type:** Geometric figure with labels and a coordinate system. * **Coordinate Axes:** Y-axis is vertical, X-axis is horizontal. The origin appears to be at the location of charge (2). * **Shapes:** An equilateral triangle is depicted. * **Points/Charges:** * Charge (1): Located at the top vertex, labeled + and 7.00 μC. * Charge (2): Located at the bottom-left vertex on the X-axis, labeled + and 2.00 μC. * Charge (3): Located at the bottom-right vertex on the X-axis, labeled - and -4.00 μC. * **Lines:** The sides of the triangle are drawn as solid lines connecting the charges. * **Distances/Lengths:** One side length is labeled as 0.500 m. Since it's an equilateral triangle, all sides have this length. * **Angles:** One internal angle of the triangle is labeled as 60.0°. Since it's an equilateral triangle, all internal angles are 60°. * **Labels and Annotations:** * Charges are labeled (1), (2), and (3) in blue handwritten circles. * Handwritten force diagrams are present to the right, labeled (1), (2), and (3) corresponding to the charges. * Diagram (1): Shows two vectors originating from a point labeled with a circle. One vector labeled F₁₂ points upwards and to the right, making an angle of 60° with a horizontal reference line. The other vector labeled F₁₃ points downwards and to the right, also making an angle of 60° with the horizontal reference line. There are also handwritten dots and arrows suggesting vector addition (parallelogram method). * Diagram (2): Shows a point labeled with a circle. A vector labeled F₂₃ points horizontally to the right. A vector labeled F₁₂ points downwards and to the right. There is a handwritten notation "-60°" near F₁₂. A dashed line is shown, possibly representing the direction of F₂₃. * Diagram (3): Shows a point labeled with a circle. A vector labeled F₃₂ points horizontally to the left. A vector labeled F₃₁ points upwards and to the left. An angle of 60° is indicated near F₃₁. A dashed line extending horizontally from the point is shown. Another vector labeled F₃₁ is drawn slightly offset, with an angle of 60° indicated relative to a horizontal dashed line. **Other Relevant Text:** μC (microcoulombs) is the unit for charge. m (meters) is the unit for distance. ° (degrees) is the unit for angles. **Mathematical Formulas/Chemical Equations:** None explicitly written in standard formula format in the main problem area, although Coulomb's Law is implied for the calculation. The handwritten annotations include vector components and angles, suggesting the use of trigonometry for force calculations. **Table Content:** No tables are present.
