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 ?cnh1995 said:Welcome to PF!
Post this question in the homework help section and fill up the three part template provided there. You are supposed to show your attempt.
I'm afraid I can't. You need to fill up the template and show some effort.joerylee palmerola said:I don't have yet my attempt solution . Our teacher gives this problem without teaching . will you please help me ?
An electric field due to a point charge is a force field that is created by a single, isolated charge. It describes the strength and direction of the force that a charged particle would experience if placed at a particular point in space near the charge.
The strength of an electric field due to a point charge can be calculated using the equation E = kQ/r^2, where E is the electric field strength, k is the Coulomb's constant, Q is the magnitude of the point charge, and r is the distance between the charge and the point in space.
Yes, the electric field due to a point charge is dependent on the sign of the charge. Like charges repel each other, so a positive point charge will create an electric field that pushes away other positive charges, while a negative point charge will create an electric field that pushes away other negative charges.
As the distance from a point charge increases, the strength of the electric field decreases. This is because the electric field follows an inverse square law, so the further away from the point charge, the weaker the field becomes.
Yes, the direction of an electric field due to a point charge can change depending on the location of the point in space. The electric field always points away from a positive point charge and towards a negative point charge, but the direction can vary at different points in space.
