Per NCERT §7.5 (eqn 7.5 onwards), the gravitational acceleration of a body INSIDE a uniform spherical shell of mass M is which?
AGM/r² where r is shell radius
BZero
CEqual to surface g
DConstant nonzero
Answer & Solution
Correct answer: B. Zero
NCERT §7.5 (Newton's shell theorem): inside a uniform spherical shell, gravitational field is zero everywhere.
