Calculating Force of n Particles in R-l Container

[MMD]

A container with radius R and height l contains n particles. If all particles in the container are equally distanced from each others by a distance and the force from each particles to the point A is f = K/ d^2 (K=constant and AB = d), please find the total force from all particles to the point A using integration (h = constant).

Please view the attachment for a figure illustrating the problem.

Thank you.
