Homework Statement
A uniform solid sphere is inside and concentric with a spherical shell.
M1=133kg ---mass of shell
R1=2.42m ---radius of shell
M2=278kg --mass of sphere
R2=1.16m --radius of sphere
a) Find the magnitude of the gravitational force exerted by the sphere and spherical shell on a particle of mass 6 kg located at a distance 0.56 m from the center of the sphere and spherical shell.
b) Find the magnitude of the gravitational force exerted by the sphere and spherical shell on a particle of mass 6 kg located at a distance 1.66 m from the center of the sphere and
spherical shell.
c)Find the magnitude of the gravitational force exerted by the sphere and spherical shell on a particle of mass 6 kg located at a distance 2.84 m from the center of the sphere and spherical shell.
Homework Equations
F=GMm/r^2
The Attempt at a Solution
For the first one, I thought that the answer should be zero because I believed that the force on point masses inside a sphere/shell was zero.
I'm not sure how to begin with the rest because I think I'm overlooking something in the first part.
