What is the x-component of the total electric field due to these two charges at a point on the x-axis?
1 answer:
Find the total x - component of the electric field at that point and get the resultant or the algebraic sum.
- The electric field is a vector as it gives the force on a unit positive test charge placed at some distance from a charge.
- The electric field due to each charge at that point on the x-axis can be found using the Coulombs formula:
.
- Then one needs to get the x-component of the electric field at the point due to each charge using the concept of the resolution of forces.
- Once the x-components are found, one needs to get the resultant or the algebraic sum of them to calculate the x-component of the total electric field.

If the distance between two charges is halved, the electrical force between them increases by a factor 4.
In fact, the magnitude of the electric force between two charges is given by:
where
k is the Coulomb's constant
q1 and q2 are the two charges
r is the separation between the two charges
We see that the magnitude of the force F is inversely proportional to the square of the distance r. Therefore, if the radius is halved:
the magnitude of the force changes as follows:
so, the force increases by a factor 4.
