Electric field due to a point charges

AI Thread Summary
To determine the charge needed at x=4.0m, y=0 for the electric field at x=4.0m, y=3.0m to be zero, the problem requires understanding the contributions of the existing charges. Participants emphasize the importance of showing an attempt at solving the problem before seeking help, as per forum guidelines. A lack of initial effort can hinder the ability to receive assistance effectively. Users encourage posting in the homework help section with a completed template. Engaging with the problem is crucial for learning and obtaining guidance.

Suppose a charge q is placed at point x=0, y=0. A second charge q is placed at point x=8.0m, y=0. What charge must be placed at the point x=4.0m, y=0 in order that the field at the point x=4.0m, y=3.0m be zero?

I don't have yet my attempt solution . Our teacher gives this problem without teaching . will you please help me ?
 
You need to show at least some thoughts or ideas about the solution, even if you can't proceed very far with it.
 

Thread 'Why measure the speed of light in one direction?'

It may be shown from the equations of electromagnetism, by James Clerk Maxwell in the 1860’s, that the speed of light in the vacuum of free space is related to electric permittivity (ϵ) and magnetic permeability (μ) by the equation: c=1/√( μ ϵ ) . This value is a constant for the vacuum of free space and is independent of the motion of the observer. It was this fact, in part, that led Albert Einstein to Special Relativity.
