Problem

A point charge q1=+2 μCq_1=+2\,\mu\text{C} is located at the origin. A second charge q2=−3 μCq_2=-3\,\mu\text{C} is kept at the point (0.30 m, 0.40 m, 0)(0.30\,\text{m},\,0.40\,\text{m},\,0). Calculate the electrostatic force F12\mathbf F_{12} acting on q1q_1 due to q2q_2. a) −0.13 i^−0.17 j^  N-0.13\,\hat i-0.17\,\hat j\;\text{N} b) +0.26 i^+0.35 j^  N+0.26\,\hat i+0.35\,\hat j\;\text{N} c) +0.13 i^+0.17 j^  N+0.13\,\hat i+0.17\,\hat j\;\text{N} d) +0.065 i^+0.086 j^  N+0.065\,\hat i+0.086\,\hat j\;\text{N}
