How Fast to Push q2 to Infinity?

In summary, two charges, q1=-9.4 μC and q2=1.2 nC with masses m1=13.4 gram and m2=2.7 gram were located 8.5 cm from each other. Charge q1 is held in place. The goal is to push charge q2 as far from q1 as possible. To find the initial velocity needed, relevant equations and an attempt at a solution are required.

Two charges, q1=-9.4 μC and q2=1.2 nC with masses m1=13.4 gram and m2=2.7 gram were
located 8.5 cm from each other. Charge q1 is held in place.

We wish to push the 2nd charge q2 as far from the 1st charge as possible.

With what initial velocity should charge q2 be pushed to send it all the way to infinity?

Hi Mike, welcome to PF!

I have moved your question to the homework forums, but before we can help we need you to list any relevant equations and show your attempt at a solution (even if you know it is wrong)
 

FAQ: How Fast to Push q2 to Infinity?

1. What is electrostatic potential energy?

Electrostatic potential energy is the potential energy that results from the interaction of charged particles. It is the energy stored within a system of charged objects due to their positions relative to each other.

2. How is electrostatic potential energy calculated?

The formula for calculating electrostatic potential energy is U = k(q1q2)/r, where U is the potential energy, k is the Coulomb's constant, q1 and q2 are the magnitudes of the charges, and r is the distance between the charges.

3. What is the relationship between electrostatic potential energy and distance?

The electrostatic potential energy between two charges is directly proportional to the magnitude of the charges and inversely proportional to the distance between them. This means that as the distance between two charges increases, the potential energy decreases.

4. How does changing the charge affect electrostatic potential energy?

As the magnitude of the charges increases, the electrostatic potential energy also increases. This is because the force between two charges is greater when the charges are larger, resulting in more potential energy within the system.

5. What is the practical application of electrostatic potential energy?

Electrostatic potential energy has many practical applications, such as in electronic devices, where it is used to store and transfer energy. It is also important in understanding the behavior of atoms and molecules, as well as the interactions between particles in various physical and chemical systems.
