Hi and welcome to PF!nw0rbrolyat said:Homework Statement
four particles are fixed in place and have charges q1 = q2 = 3e, q3 = 7e, and q4 = -28e. Distance d = 6.7 µm. What is the magnitude of the net electric field at point P due to the particles?
Homework Equations
Im not sure what form of the magnitude equation to use for this.
Im new to this forum and am always needing Physics help. Thanks to you all!
Taylor
I think by e they mean the electric charge of an electron. Isn't [tex]\mu=10^{-6}m[/tex]?nw0rbrolyat said:for q1 the equation I would use is E1=(8.99e9)(3e/(.0067m)^2).
Do I have this setup correctly? I am not quite sure what to do with the e's will an e remain in the answer?
A Net Electric Field is the combined electric field produced by multiple charges in a given region of space. It is a vector quantity that describes the strength and direction of the electric field at a specific point.
The Net Electric Field is calculated by adding the individual electric fields produced by each charge at a specific point. This can be done using the formula E = kq/r^2, where E is the electric field, k is the Coulomb's constant, q is the charge, and r is the distance between the charge and the point of interest.
Yes, the Net Electric Field can be zero if the individual electric fields produced by the charges cancel each other out. This can happen if there are equal and opposite charges present in the region or if the charges are arranged in a way that their individual electric fields cancel out.
The Net Electric Field is a vector quantity that describes the strength and direction of the electric field at a specific point, while Electric Potential is a scalar quantity that describes the amount of potential energy per unit charge at a specific point. The Net Electric Field is dependent on the charges present in the region, while Electric Potential is dependent on the position and configuration of the charges.
The Net Electric Field is used in many practical applications such as designing electrical circuits, determining the behavior of charged particles in electromagnetic fields, and calculating the forces experienced by objects in electric fields. It is also used in medical imaging techniques such as MRI and in the development of electronic devices.
