Question

which factors affect the strength of the electric force between two objects?
the mass of the objects and the distance between the objects
the amount of charge on the objects and the type of charge on the objects
the distance between the objects and the amount of charge on the objects
the mass of the objects and the amount of charge on the objects

Explanation:

According to Coulomb's law, the electric force \(F = k\frac{q_1q_2}{r^{2}}\), where \(k\) is a constant, \(q_1\) and \(q_2\) are the amounts of charge on the two objects, and \(r\) is the distance between the two objects. So the electric force depends on the amount of charge on the objects (\(q_1\) and \(q_2\)) and the distance between the objects (\(r\)). The mass of the objects is not involved in the formula for electric force, and the type of charge (positive or negative) only affects the direction (attractive or repulsive) of the force, not its magnitude.

Answer:

the distance between the objects and the amount of charge on the objects
