Question

Exercise 13.31 10 of 10 Constants A uniform, solid, 1500.0 kg sphere has a radius of 5.00 I. Find the gravitational force this sphere exerts on a 2.00 kg point mass placed at the following distances from the center of the sphere: (a) 5.05 m, and (b) 2.70 m Submit Part B F. Submit

Answer 1

$F=GMm/R^{2}$

Part A

$R=5.05m$

$F=6.67408*10^{-11}*1500kg*2kg/(5.05m)^{2}$

$F=6.67408*10^{-11}*1500*2/5.05^{2}$

ANSWER: ${\color{Red} F=7.85*10^{-9}N}$

=======================

Part B

$R=2.7m$

$F=6.67408*10^{-11}*1500kg*2kg/(2.7m)^{2}$

$F=6.67408*10^{-11}*1500*2/2.7^{2}$

ANSWER: ${\color{Red} F=2.75*10^{-8}N}$
