alleryGravitational potential at the centre of a uniform spherical shell of mass M and radius R:
AGM/R
B-GM/R²
C-GM/R
DZero
Answer & Solution
Correct answer: C. -GM/R
Inside a uniform spherical shell, gravitational FIELD is zero but POTENTIAL is constant (equal to value at surface): V = -GM/R. (Field is the gradient of potential; constant potential gives zero field.)
