| Abstract: | The potential distribution in space, charge density, the interaction between the needle charge and electric sphere when the needle charge exists outside of the electric sphere were discussed. The results show that electric sphere and the needle charge can attractive each other, even if they carry homogeneous charge. |

| Keywords: | electric sphere potential charge density interaction |
