Steps to Find Magnitude of an Electric Field
These are the simple steps to find the magnitude of an electric field created at a distance from the charge point. Follow these guiding principles and get the result.
- Obtain the values of the charge point and distance from the point.
- Multiply the charge point by the Coulomb's constant.
- Divide the product by the square of the distance to check the magnitude of the electric field.
Electric Field & Formula
An electric field is the volume of area that exerts a force on charges - attracts or repels. It can be created by electric charges. The unit of the electric field is newton per coulomb or volt per meter. The amount of electric field can be measured using an electrometer.
The electric field equation can be defined as
E = kQ/r²
Where,
E is the magnitude of electric field
k is the Coulomb's constant and its value is 1/(4π╔¢0) = 8.9876 x 109 N-m²/C²
Q is the charge point
r is the distance from the point
Example
Question: What is the electric field due to a point charge of 15 μC at a distance of 2 meters away from it?
Solution:
Given that
Charge point Q = 15 μC = 15 x 10-6 C
Distace from the point r = 2 m
Magnitude of an electric field at an arbitary point from the charge is E = kQ/r²
E = 8.9876 x 109 x 15 x 10-6/2²
= 134.814 x 103/4
= 33.7035 x 103 N/C
Therefore, the electric field due yo a point charge is 33.7035 x 103 N/C.
