Based on the equation for gravitational force, the value of radius (r) is equal to r = √(GM₁M₂/F).
A gravitational force can be defined as a universal force of attraction which acts between two (2) physical objects, especially by pulling them together.
Mathematically, the gravitational force between two (2) planetary objects is given by this formula:
F = GM₁M₂/r²
Where:
Making r the subject of formula, we have:
Fr² = GM₁M₂
Divide both sides by F, we have:
r² = GM₁M₂/F
Taking the square root of both sides, we have:
r = √(GM₁M₂/F)
