A) Yes. we don't have enough information so this can not be determined.
B) No, it would just be an outlier.
The surface of a spherical conductor of radius a is kept at a temperature of u(φ)=300K+50K cos(φ). The temperature inside is governed by the Laplace equation. Find an expression for the temperature everywhere inside the sphere. Evaluate the temperature at the center of the sphere.
Answer:
Both expressions are = to 11 when x is 2.
Therefore, the expressions are equivalent.
