We assume a shell element of thickness dp and of radius p.

then resistance is given by

dR = rdp/4πp²

R = (r/4π) $\int_{a}^{b}$ dp/p² = (r/4π)(1/a – 1/b).

Hope it clears. If you like anser then please approve it.

Three identical balls are placed on a frictionless horizontal surface touching each other. They stick to each other because of adhesive. Another ball of same radius and mass m is placed over the void created by the three balls. Find the forces applied by the balls kept on the floor to each other if the system remains in equilibrium.
