How does adding a constant Vo affect the potential in Griffith's Ex 3.8?

Homework Statement

In the example of the grounded conducting sphere in the uniform electric field (Ex. 3.8), suppose we keep the constant of integration in V for large r, so that V -> EorPlcos$$\theta$$ + Vo the electric field at large r is unchanged. Find V outside the sphere under these conditions. What is physically different?

The Attempt at a Solution

I think this is the same problem. I was just wondering if l = 2? And what will happened to the Vo??

The boundary condition is changed this will change the outcome when calculating the field outside

If I understand your question correctly, you just have to add V_0 to the previous answer for the potential anywhere.
