1. Explain how the charges on objects determine the electric force between them. (Lesson 2) The greater the charges on the objects the greater the electric force between them. Similarly if the distance between the objects decreases the electric force also increases.
Electric force is directly proportional to the product of the charges on the objects and inversely proportional to the square of the distance between them. Mathematically, the formula for electric force can be given as:
F = k * |q1 * q2| / r^2
where F is the electric force, k is Coulomb's constant, q1 and q2 are the charges on the objects, and r is the distance between the objects.
Therefore, the charges on the objects play a crucial role in determining the electric force between them. The larger the charges, the stronger the force, and vice versa. Additionally, if the charges are of opposite polarity, they will attract each other, while if they are of the same polarity, they will repel each other.
Overall, the charges on objects interact with each other through the electric force, which is dependent on the magnitudes of the charges and the distance between them.
