Its a tube with 3 sphere's on it. sphere 2&3 are connected in together in a rope & sphere one(bottom) has a negative charge & I'm supposed to solve for the tension of the rope.

## 1. What is the equation to calculate tension using Coulomb's Law?

The equation to calculate tension using Coulomb's Law is T = (k * Q1 * Q2) / r^2, where T represents the tension force, k is the Coulomb's constant (8.99 x 10^9 N*m^2/C^2), Q1 and Q2 are the magnitudes of the charges, and r is the distance between the charges.

## 2. How is Coulomb's Law used in calculating tension?

Coulomb's Law is used to calculate the electrostatic force between two charged objects. In the context of tension, it can be used to determine the force needed to keep two charged objects suspended at a certain distance from each other.

## 3. Can the equation for tension using Coulomb's Law be applied to any type of charged object?

Yes, the equation for tension using Coulomb's Law can be applied to any type of charged object, as long as they have a defined magnitude of charge and distance between them.

## 4. What units are used in the equation for tension using Coulomb's Law?

The units used in the equation for tension using Coulomb's Law are Newtons (N) for the tension force, Coulombs (C) for the magnitude of charge, and meters (m) for the distance between the charges. The Coulomb's constant (k) has units of N*m^2/C^2.

## 5. How does distance between the charges affect the tension calculated using Coulomb's Law?

The tension calculated using Coulomb's Law is inversely proportional to the square of the distance between the charges. This means that as the distance between the charges increases, the tension force decreases. Conversely, as the distance decreases, the tension force increases.
