उत्तर

The gravitational force is much weaker than other forces in nature.

Explanation:

  • Gravity is far weaker than electromagnetic and nuclear forces at atomic and molecular scales.
  • However, because mass is always positive and bodies like planets and stars are huge, gravity controls astronomical motion.
