3 d plot and 1 2d subplot

I have an equation for ploting;

x=1 to 10 nanometers ;

y=0.5 to 2 nanometers;

and k=1 to 10;(not nanometers it is a multiplication)

the equation is he equation is:

f=8.854187817.*(x.*x.*k.^2)/(y.*y);

i used

x = linspace(1,10,15);
y = linspace(0.5,2,15);
k = linspace(1,10,15);
[X,Y,K] = meshgrid(x, y, k);
f = 8.854187817.*(X.*X.*K.^2)./(Y.*Y);
pointsize = 36;
scatter3(X(:),Y(:),K(:),pointsize,f(:))

now the question is when i click on the point on the values how can i genarate a plot for F and k? x=k f=y; 2d?
