The factors that affect the strength of the electrical force are:
A) Distance between objects - The strength of the electrical force decreases as the distance between the charged objects increases.
B) Magnitude of the charges - The strength of the electrical force is directly proportional to the product of the magnitudes of the charges involved.
C) Mass of objects - This is not a factor that affects the electrical force. The mass of the objects does not influence the strength of the electrical force between charged objects.
D) Size of charges - This is a bit misleading in terminology; however, if "size of changes" refers to the magnitude of the charges, then it is related to factor B.
Therefore, the correct answers are:
- A) Distance between objects
- B) Magnitude of the charges
If you meant "size of changes" to be similar to "magnitude of charges" then you can consider D as applicable in context. Otherwise, D could be ambiguous.
