Calculating Electric Potential

K=9e9

Q1=6e-9

Q2=2e-9

X1=0.00

X2=0.01

x=0.02

dx=0.001

xminus=x-dx

xplus=x+dx

Vminus=K*Q1/(xminus-X1)+K*Q2/(xminus-X2)

Vplus=K*Q1/(xplus-X1)+K*Q2/(xplus-X2)

E=-(Vplus - Vminus)/(2*dx)

print("Ex = ",E,"N/C")

E1=K*Q1/(x-X1)**2

E2=K*Q2/(x-X2)**2

print("Ex1 = ",E1+E2,"N/C")

  

plot.plot(E,'ro--')

plot.plot(E1+E2,'o')

plot.show()

Output:-
