Electrostatics

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