No work is done in taking a positive charge from one point to other inside a positive charged metallic sphere, while outside the sphere work is done in taking the charge from one point to other (towards the sphere). Explain.

Statement-1 : No work is done in taking a small positive charge from one point to other inside a positively charged metallic sphere while outside the sphere work is done in taking the charge towards the sphere. Neglect induction due to small charge. Statement-2 : Inside the sphere electric potential is same at each point, but outside it is different for different points.
