According to gravitation book, it states that if the centres of 2 planets, each of mass M and separated by a distance r and you have a point halfway between the centres of the planets, the gravitational field strength at that point is zero.

Why is there a point between Earth and moon where gravitational field strength is zero?

  • The net force is zero at neutral point X because the gravitational force due to the Earth is equal to and opposite to that due to the Moon. This is the result of Newton's First Law.
  • Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.
  • If the earth were 36,000 km in circumference, with the same mass and length of day, gravity would be zero near the equator. Geostationary orbits are at this altitude.
