Per NCERT §4.6 example, the third-law REACTION to Earth pulling a stone downward (with force mg) is which force?
AGravity is one-sided
BEarth pushes stone upward with normal force
CStone pulls Earth upward with force mg
DReaction is zero by symmetry
Answer & Solution
Correct answer: C. Stone pulls Earth upward with force mg
NCERT §4.6: the stone exerts an equal and opposite force on the Earth. Effect is negligible because of Earth's huge mass.
