Three point charges of magnitude $\displaystyle 5 \mu C, 0.16 \mu C$ and $\displaystyle 0.3 \mu C$ are located at the vertices $\displaystyle A, B, C$ of a right angled triangle whose sides are $\displaystyle A B=3 \mathrm{~cm}, B C=3 \sqrt{2} \mathrm{~cm}$ and $\displaystyle C A=3 \mathrm{~cm}$ and point $\displaystyle A$ is the right angle corner. Charge at point A experiences \_\_\_\_ N of electrostatic force due to the other two charges.
