The electrostatic force between two charges is originally F. Which expression represents the new electrostatic force between the two charges if one charge doubles and the other one is divided by three?
• 1/6
• 3/2 *
• 2/3
• 6
To determine the new electrostatic force between two charges, we can use Coulomb's law, which states that the electrostatic force between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
Let's denote the original charges as Q1 and Q2, and the initial electrostatic force as F.
Given that one of the charges doubles and the other charge is divided by three, the new charges can be represented as 2Q1 and Q2/3.
Using Coulomb's law, the new electrostatic force can be calculated as:
F_new = k * (2Q1) * (Q2/3) / r^2
Where k is the proportionality constant (which we won't consider in this explanation), and r is the distance between the charges.
Simplifying the expression:
F_new = (2/3) * (Q1 * Q2) / r^2
Comparing this expression with the given options, it matches the expression 3/2. Hence, the correct answer is 3/2.
