Question

Which is the correct statement below?

  1. A. The force with which the earth attracts all objects towards itself is called gravitational force. (Correct answer)
  2. B. The force with which the earth does not attract all objects towards itself is called gravitational force.
  3. C. The force with which the earth distracts all objects from itself is called gravitational force.
  4. D. None of the above

Correct Answer

Option A — The force with which the earth attracts all objects towards itself is called gravitational force.

Detailed Solution & Explanation

The correct answer is The force with which the earth attracts all objects towards itself is called gravitational force.

Key Points

  • Gravitational force is the attraction the earth exerts on every object, pulling it towards the centre of the earth.
  • Options B and C invert the definition — describing the earth as *not* attracting, or as repelling objects — and are therefore wrong.

Additional Information

  • Newton's law of universal gravitation: F = G·m₁m₂/r², with G = 6.674 × 10⁻¹¹ N·m²/kg².
  • The acceleration due to gravity, g ≈ 9.8 m/s², is slightly greater at the poles than at the equator because the earth is not a perfect sphere.
  • Gravitation is a non-contact force, acting across a distance, and is always attractive — never repulsive, unlike magnetic and electrostatic forces.
