spherical

...of 167 m.? An evacuated spherical diving bell containing a camera is in the ocean at a depth of 167 m. It has a flat, transparent, circular port with a diameter of 17.5 cm. Find the magnitude of the total force on the port (use rseawater) = 1025 kg/m3).

That would all depend on the masses of the two, and the average distance apart. Link to formula:
