Which of the following statements is incorrect about gravitational force?
It’s attractive (option 1 correct), follows inverse-square (option 2 correct), and is conservative (option 4 correct). Option 3 is incorrect as it is not limited to Earth. As per NCERT, applying relevant law/formula with correct units and sign convention leads to It acts only near Earth. This satisfies dimensional consistency and physical conditions given, so option C is scientifically correct.
