    Sorry I'm not much of an artist but here you go.

    They both have field lines "radiating" outwards but the 6nC will have about 3 field lines to every 2 of the 4nC charge. Because the 6nC has a stronger field, its field lines will look as if they are pushing the 4nC field lines back.

    Told you I wasn't a great artist - I just counted the number of lines I drew around each charge. The 4nC should have about 8 lines around it since I've put 11 round the 6nC charge
