What does the inverse-square nature of gravitational force imply about its range?
F∝1/r2 means the force decreases with distance but never reaches zero, implying an infinite range, as it extends indefinitely, though it weakens rapidly. As per NCERT, applying relevant law/formula with correct units and sign convention leads to It has an infinite range. This satisfies dimensional consistency and physical conditions given, so option B is scientifically correct.
