PART B AND PART C

I Review Newton's law of gravity and Coulomb's law are both inverse-square laws. Consequently, there should be a "Gauss's law for gravity." Part B A spherical planet is discovered with mass M, radius R, and a mass density that varies with radius as p= Po (1 - r/2R) , where Po is the density at the center. Determine po in terms of M and R. Hint: Divide the planet into infinitesimal shells of thickness dr, then sum (i.e., integrate) their masses. Express your answer in terms of the variables M and R. • View Available Hint(s) Πνο ΑΣφ Po = Submit Previous Answers Part C Gauss's law for gravity: fg. dA = -4TGMin - Find an expression for the gravitational field strength inside the planet at distancer< R. Express your answer in terms of the variables M, r, R, and the gravitational constant G. • View Available Hint(s) Πνα ΑΣφ ?
