How Do You Solve Basic Electric Field Problems?

[sakrei]

This is a pretty basic problem, but I am a little bit lost. I'm not really sure where to start. Can anyone point me in the right direction? i have all the formulas but its not really helping . The problem is #3 on this link:

Please, show your own work: https://www.physicsforums.com/showthread.php?t=94379

Start by writing down all the forces acting on the particles.

Sure, I would be happy to help guide you in the right direction. It is important to first understand the concept of electric fields and how they are calculated. The electric field is a vector quantity that describes the strength and direction of the electric force at any given point in space. It is calculated by dividing the electric force by the charge at that point.

To solve the problem #3 on the given link, you will need to use the formula for electric field, E = F/q, where E is the electric field, F is the electric force, and q is the charge. Then, you will need to determine the magnitude and direction of the electric force using Coulomb's law, F = k*q1*q2/r^2, where k is the Coulomb's constant, q1 and q2 are the charges, and r is the distance between them.

It may also be helpful to draw a diagram and label all known values to visualize the problem. Make sure to pay attention to the units and use consistent units throughout your calculations. I recommend breaking down the problem into smaller steps and checking your work along the way. If you are still having trouble, I suggest seeking help from a classmate or your instructor. I hope this helps guide you in the right direction. Good luck!
