Answer:
16
Explanation:
The magnitude of the electrostatic force between two charged particles is given by
where
k is the Coulomb's constant
q1, q2 are the charges of the two particles
r is the separation between the particles
In this problem, the initial force between the particles is F.
Later, the distance between the two particles is increased by four, so
r' = 4r
So, the new force between the particles will be
So, the new force decreases by a factor of 16.

An example of an inverse relationship is the one between pressure and volume of an ideal gas
Explanation:
Boyle's law states that:
<em>"For a gas kept at a constant temperature, the pressure of the gas is inversely proportional to its volume" </em>
Mathematically,
where p is the pressure of the gas and V its volume.
The relationship can be written as
Therefore it is an example of inverse relationship, because:
- As the volume increases, the pressure decreases
- As the volume decreases, the pressure increases
