2024 F = ma Exam — Question 22

A spherical shell is made from a thin sheet of material with a mass per area of σ. Consider two points, P1 and P2 , which are close to each other, but just inside and outside the sphere, respectively. If the accelerations due to gravity at these points are g1 and g2 , respectively, what is the value of |g1 − g2 |?
