Applying Gauss's Law for Gravitation Using Gauss's law for gravitation (derived in part (b) of Problem 22.59),
Question:
(a) For any spherically symmetric mass distribution with total mass M, the acceleration due to gravity outside the distribution is the same as though all the mass were concentrated at the center.
(b) At any point inside a spherically symmetric shell of mass, the acceleration due to gravity is zero.
(c) If we could drill a hole through a spherically sym metric planet to its center, and if the density were uniform, we would find that the magnitude of g is directly proportional to the distance r from the center. We proved these results in Section 12.6 using some fairly strenuous analysis; the proofs using Gauss's law for gravitation are much easier.
Distribution
The word "distribution" has several meanings in the financial world, most of them pertaining to the payment of assets from a fund, account, or individual security to an investor or beneficiary. Retirement account distributions are among the most...
