Q.156 has too many problems (IMHO). Earth will disintegrate so no mining, some type of ball pen can work (even used by astronauts), technically DTH connection can still work. Q.158 Pump will do work because not all water (most) seeps down.

Earth won't disintegrate as gravity is not the only thing that holds the things together. There are intermolecular forces also, some of which are electromagnetic in nature which has nothing to do with gravity. Loss of gravity will make things difficult but not impossible. Like imagine, space has no gravity but yet it's not disintegrating. And yes, some type of ball pen do work without gravity, but they are not conventional one's. In exams your always asked mostly about conventional things. If there ain't a satellite, then obviously there can't be DTH.
