Two point charges are located on the $x$ -axis: a charge of $+6.0 \mathrm{nC}$ at $x=0$ and an unknown charge $q$ at $x=0.50 \mathrm{m}$ No other charges are nearby. If the electric field is zero at the point $x=1.0 \mathrm{m},$ what is $q ?$

Key Concepts

Coulomb's Law

Coulomb's Law describes how the electric field (or force) produced by a point charge depends on the magnitude of the charge and the square of the distance from it. This law is fundamental for calculating the strength and direction of the electric field that a charge produces at any point in space, forming the basis for understanding interactions between multiple point charges.

Electric Field Due to a Point Charge

This concept explains that a point charge generates an electric field that radiates outward (if the charge is positive) or inward (if the charge is negative), with a magnitude that is proportional to the charge and inversely proportional to the square of the distance from the charge. It is crucial for determining how individual charges contribute to the overall electric field at a certain point.

Superposition Principle

The superposition principle states that the net electric field created by multiple charges is the vector sum of the individual electric fields produced by each charge. This principle is key when analyzing situations where fields from different sources interact, especially in finding points where the total electric field is zero, due to the cancellation of the effects from each charge.
