Answer:
a. Increases
b. Two objects that have opposite charges
Explanation:
a. As the amount of charge on two objects increases, the strength of the electrical force between the objects increases. decreases. varies. remains the same.
According to Coulomb's law, the electrical force, F between two charges q and Q is directly proportional to the product of the charges.
So, F ∝ qQ
So, if q and Q increase, their product increases and thus, the strength of the electrical force between them increases.
So, if the amount of charge of two objects increases, the strength of the electrical force between the objects increases.
b. For which pair of objects would adding the same amount of electrons to each object result in a decrease in the electric force? two positively charged objects two negatively charged objects two objects that have no charge two objects that have opposite charges
Since according to Coulomb's law, the electrical force, F between two charges q and Q is directly proportional to the product of the charges.
So, F ∝ qQ
If the same amount of electrons are added to both charges and the charges are opposite in sign, the magnitude of one charge increases while that of the other charge decreases. so the product qQ decreases and thus F decreases.
So, the electric force decreases when the same amount of electrons is added to two objects that have opposite charges.
