cwrw238 · Answer

inverse variation

y = k/x^2   where k is some constant

so let y = the force and x = distance and plug in the given values to find k

now replace k by this value , plug in the force = 36 and solve for x

@cwrw238 36=k/x^2 would K be any number?

cwrw238 · Answer

as i said you can find k by putting y = 64 and x = 9 in the formula and solving for k

cwrw238 · Answer

64 = k / (9^2)
