The formula for calculating the force between two point charges is given by Coulomb's Law, which states that the force (F) is equal to the product of the two charges (q1 and q2) divided by the square of the distance (r) between them, multiplied by a constant (k) known as the Coulomb's constant. Mathematically, it can be written as F = (k * q1 * q2) / r^2.
Yes, the force between two point charges can be negative. This happens when the two charges have opposite signs, i.e. one is positive and the other is negative. In this case, the force between them is attractive, pulling the two charges towards each other.
If the distance between two point charges is doubled, the force between them decreases by a factor of four. This is because the force is inversely proportional to the square of the distance between the two charges. So, as the distance increases, the force decreases.
The magnitude of the charges has a direct impact on the force between two point charges. As the magnitude of the charges increases, the force between them also increases. This is because the force is directly proportional to the product of the two charges. So, larger charges will experience a stronger force compared to smaller charges.
Yes, the force between two point charges can be zero. This happens when either one or both of the charges are zero, or when the distance between them is infinity. In these cases, there is no force acting between the two charges.
