Two point charges are separated by 25.0cm (see the Figure 1).

Question

Part A: Find the magnitude of the net electric field these charges produce at point A.

Part B: Find the magnitude of the net electric field these charges produce at point B.

Part C: What would be the magnitude of the electric force this combination of charges would produce on a proton at A?

Revelant knowledge

Electric Field: Electric field can be described as a vector and is governed by the laws of addition in a vector form. In the case of electric fields that are in parallel and symmetrical, they are subtracted or added to create the electric field. The electric field close to an electric point is determined by: in which E is the power of electric fields, q is the size of a point charge, r is the distance that a point is from the charge at its source, and k is Coulomb's constant.

Concepts and Reason

Electric force and electric field are the two required concepts to resolve this problem.

First, combine the fields generated by both the charges at point A to find the net electric field at . The net field at B can later be found by adding the fields from both the and charges. Find the electric force created by these charges on a proton in point A using relation between charge and electric field.

Fundamentals

An electric field is an area around a charged particle that experiences a force. The charge is directly proportional and the distance between the location where the field will be established and the charge is inversely proportional.

Here, q is the magnitude of a point charge, r is the distance a point is away from the point charge

The electric force is the force felt by a charged particle within an electric field. The electric force is the result of the charge and the electrical field.

F = qE

Here, q is the charge and E is the electric field.
