What is the effect of gravitational force between two bodies if the separation between them doubled?

Text Solution

Solution : when distance (d) between two bodies is a double, the gravitational force of attraction between them becomes one fourth. To keep this force constant, mass of one of the bodies has to be made 4 times.

The correct answer is decreases.

• If the distance between two particles is increased, then what is the effect on the gravitational force between them decreases.
  • Since the gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces.
  • So as two objects are separated from each other, the force of gravitational attraction between them also decreases.
• Newton's law of universal gravitation
  • \(F= {G (m1 * m2 )\over{r^2}}\)
    • F = force
    • G = gravitational constant
    • m1 = mass of object 1
    • m2 = mass of object 2
    • r = distance between centres of the masses
