Example 1 · difficulty 3/5
A charge +1 μC is at the origin. Charges +2 μC and −1 μC are placed at (0.30 m, 0) and (0, 0.30 m), respectively. Using k = 9 × 10⁹ N m² C⁻², what is the resultant force on the charge at the origin?
- A. 0.100 N vertically upward
- B. 0.200 N horizontally to the left
- C. 0.300 N toward the upper left
- D. Approximately 0.224 N toward the upper left
