Two equal point charges each of \[3\mu C\] are separated by a certain distance in meters. If they are located at \[(\hat{i}+\hat{j}+\hat{k})\] and \[(2\hat{i}+3\hat{j}+\hat{k})\], then the electrostatic force between them is

• A. \[9\times {{10}^{3}}N\]
• B. \[16\times {{10}^{-3}}N\]
• C. \[{{10}^{-3}}N\]
• D. \[9\times {{10}^{-2}}N\]
