Two point charges are $q1=2.0$ microcoulombs and $q2=3.0$ microcoulombs. For the force on $q2$, the displacement vector is $\overrightarrow{R}=0.30\hat{i}+0.40\hat{j}$ meters. Using $k=8.99\times {10}^9$ ${\text{Nm}}^2{\text{/C}}^2$, what is the force vector?

• A. $1.29\hat{i}+1.73\hat{j}$ $\text{N}$
• B. $0.129\hat{i}+0.173\hat{j}$ $\text{N}$
• C. $0.173\hat{i}+0.129\hat{j}$ $\text{N}$
• D. $0.432\hat{i}+0.432\hat{j}$ $\text{N}$

Answer: (B)
