Two point charges \( q_1 = 3\,\mu\text{C} \) and \( q_2 = -4\,\mu\text{C} \) are placed at points \( (2\hat{i}+3\hat{j}+3\hat{k}) \) and \( (\hat{i}+\hat{j}+\hat{k}) \) respectively. Force on charge \( q_2 \) is ______ \( \text{N} \). [Take \( \dfrac{1}{4\pi \varepsilon_0} = 9\times 10^{9} \) SI units]
