Answer:
B) Electric forces and magnetic forces are different aspects of a single electromagnetic force.
C) The operation of a motor depends on the relationship between electric and magnetic forces.
Explanation:
A) The definition of electric force:
two charged objects is directly proportional to the product of the quantity of charge on the objects and inversely proportional to the square of the separation distance between the two objects.
Electromagnetic force:
a type of physical interaction that occurs between electrically charged particles.
They are no identical so the statement is not true.
B) A magnetic doesnt have to be moving for a magnetic field to exist because when they are near each other and not moving there is a magnetic field.
So this statement is not true
