The net electric field is the vector sum of the components of the electric
field produced by the two charges.
The values of the magnitude and direction of the net electric field at the origin (approximate values) are;
- 12.6 ° above the negative x–axis
<h3>How are the net electric field magnitude and direction calculated?</h3>
The possible questions based on a similar question posted online are;
(a) The net electric field at the origin.
The electric field due to charge q₁ is given as follows;
Which gives;
Which gives;
Therefore;
![\vec {E} = \left[ 21.6 \, N/C - 150 \, N/C \right] \left( \hat x \right) + \left(28.8 \, N/C \right) \left( \hat y \right)](https://tex.z-dn.net/?f=%5Cvec%20%20%7BE%7D%20%3D%20%5Cleft%5B%2021.6%20%5C%2C%20N%2FC%20-%20150%20%5C%2C%20N%2FC%20%5Cright%5D%20%5Cleft%28%20%5Chat%20x%20%5Cright%29%20%2B%20%5Cleft%2828.8%20%5C%2C%20N%2FC%20%5Cright%29%20%5Cleft%28%20%5Chat%20y%20%5Cright%29)
The magnitude of the net electric field is therefore;
E = 
≈ 131.6
- The magnitude of the net electric field at the origin is E ≈<u> 131.6 N/C</u>
(b) The direction of the net electric field at the origin.

The procedures that can be regarded as part of descartes’s rules in science are;
<em>keeping a detailed record of the procedure and results of a scientific experiment</em>
<em>conducting an experiment to confirm the effects of gravity on Earth</em>
<em>solving an expression in steps using the order of operations</em>

- René Descartes can be regarded as one of the philosopher that brings sbout invention of analytical geometry as well as skepticism which serve as essential part of the scientific method.
- With his analytical geometry relationship between separate fields of geometry and algebra were established.
Descartes has four rules which help him to have a true conclusion about his research, and they are :
- Doubting of everything is allowed
- Every bulk problem must be broken into parts
- Solving of the simplest problem must come first.
- Be thorough.
Therefore, descartes’s rules can be regarded as essential part of scientific method

A reproductive combination between living parent organisms which produces hybrids is: c. when members of closely related species reproduce.
<h3>What is reproduction?</h3>
Reproduction can be defined as a biological process through which all living parent organisms produce their offspring, especially through mating.
<h3>What is a species?</h3>
A species is a biological classification of related organisms that have the same or similar characteristics, and they are capable of mating (breeding) with one another in a cycle or different seasons.
During the reproduction process, a reproductive combination between living parent organisms which would produce hybrids is usually when members of closely-related species reproduce.
