//Example 29.4

Q1=10*10^-6;//First Charge in Coloumbs
Q2= 20*10^-6;//Second Charge in Coloumbs
r=0.02;//Distance between the charges in metres
K=9*10^9;//Value of constant (1/(4*pi*ε0))
V1=Q1*K*2/r;//Electric Potential due to First Charge
V2=Q2*K*2/r;//Electric Potential due to Second Charge
V=V1+V2;//Net Potential
