Please Please solve it as soon as possible . use any programming language u want

Please write ur own computational method that u used , I will directly thumps up

4) (15%) Consider a very long rectangular capillary tube of edge length 10nm. This tube is filled with electrolyte solution. If three sides of the tube where held at a potential of 1 V, while the fourth side is held at zero potential. Find the electrostatic potential of the system by solving av av + - k2V = 0 dx2 * ay2 With the boundary conditions V(0,x) = 1.0,V(x, 10) = 1.0,V(0,y) = 1.0 and V(10,y) = 0 Solve the equation above for different values of k to plot V(5,5) as a function of k for k between 0 and 10
