Use hypothesis two, which claims that if an object is an insulator, its electrons will stay in their vicinity of their atoms , to explain why the uncoated Styrofoam ball is still attracted to the rod after touching it...

Can you help here ?

anonymous · Answer

The hypothesis means that the electrons won't conduct from the insulator (styrofoam) to the rod (maybe also another insulator). This means both objects will retain their non-zero charge, even though they are in contact.

Then, how can they get charged in the first place ??

anonymous · Answer

That's an observation that suggests the hypothesis is incorrect.
