Force of attraction is #2.647xx10^9# Newtons

As the charges are in opposite direction, the force is that of attraction between the two.

Force is given by #(kxxQ_1xxQ_2)/d^2#, where #k=9.0xx10^9# #Nm^2/C^2#

As #Q_1=-5C# and #Q_2=1C#

and #d^2=(-3-1)^2+(4-3)^2=16+1=17#

Hence, Force is #(9.0xx10^9xx1xx5)/17=2.647xx10^9# Newtons
