Between concentric spheres the potential obtained from Laplace's equation varies

  • A.as the inverse square of the radius
  • B.as the inverse of the radius
  • C.as the logarithm of the radius
  • D.linearly with the radius

Answer: B

The spherical radial Laplacian integrates to give a constant over the radius plus another constant, and differentiating that returns the inverse square field of a point charge. The three one-dimensional cases give the three standard potential dependences.
