1. The problem statement, all variables and given/known data I'm working on a homework problem which requires me to roughly sketch electric field lines. The object on the left is neutral and grounded, the object on the right was just struck by lightning (and therefore very negatively charged) and I assume that the neutral object in the middle should now be polarized with + to the right and - to the left. 2. Relevant equations None. 3. The attempt at a solution I know that the negatively charged object will have lots of lines pointing towards it (including a few from the positive half of the dipole), and I assume that the dipole should be drawn with a line or two going from its positive side towards it's negative side, but I am unsure what happens around the neutral object on the left. Should there be any lines from the dipole to (or from) the neutral object? Or from the negative object on the right? Each of the objects are conductors, if that makes a difference.
