Final answer:
The potential of a non-uniformly charged sphere can be the same as that of a point charge at points outside the sphere, assuming the total charge is equal, but will generally differ inside the sphere due to varying charge distribution.
So, the correct answer is (b) No.
Step-by-step explanation:
The potential of a non-uniformly charged sphere can be the same as that of a point charge at certain points. When we consider the region outside the sphere, the entire charge of the sphere can be thought of as being concentrated at its center, thereby acting like a point charge.
Hence, for points outside the sphere, the electric potential created by a non-uniformly charged sphere can resemble that of a point charge if the total charge is equal.
However, at points inside the sphere, the potential would generally be different because the charge distribution affects the potential differently at different points within the sphere.
To summarize, the potential outside can be the same, while the potential inside will differ due to non-uniform charge distribution.
