    F1(applied by charge at 8cm on 2cm charge)=9×10^9×20×10^-6×20×10^-6÷36×10^-4 After solving F1=1000N F2(applied by charge at 16cm on 2cm )=9×10^9×20×10^-6×20×10^-6÷196×10^-4 F2=9000÷49N F=F1+F2 F=1000+9000/49=1.2×10^3N [We don't count force applied by charge at origin (0)and charge at 4cm bcoz they both mutually cancel each other due to opposite direction]
