Answer:
Magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. It is the basic force responsible for such effects as the action of electric motors and the attraction of magnets for iron. Electric forces exist among stationary electric charges; both electric and magnetic forces exist among moving electric charges. The magnetic force between two moving charges may be described as the effect exerted upon either charge by a magnetic field created by the other.

Explanation:
C decreased the factor cuz the max is smaller
The mathematical and proportional relationship between mL and
said us that
is equivalent to 1mL.
If the density is considered as the amount of mass per unit volume we will have to

here,
m = mass
V = Volume
Replacing we have that


As
we have that the density in g/mL is,
