Question

The force between two poles is proportional to: the inverse of the pole strengths, the distance between the poles, the inverse of the distance between the poles, the inverse square of the distance between the poles

Answer 1

the inverse square of the distance between the poles

Step-by-step explanation:

Answer 2

The force between two poles is given by the formula:
F=mi*q1*q2/4*pi*r
where
F is force in newtons
q1 and q2 are magnitudes of the two poles
mi is the permeability of the medium
r is the distance between the poles
According to this formula the following statement is true:
The force between two poles is proportional to the inverse square of the distance between the poles.
