In physics, the electric charge is a fundamental property of matter that causes it to experience a force when placed in an electromagnetic field. This can be demonstrated by placing two point charges on a graph paper and observing how they are attracted to one another. In this post, we will discuss what happens when we place two point charges at different distances apart from each other on the x-axis. The first point charge, a -15.0 nc point charge is placed 15.0 cm from the second point charge, a +20.0 nc point charge on the x-axis and both have an identical magnitude of 20.00 Coulombs (C). We can use this information to predict what would happen when we place two charges at varying distances apart from each other because they will experience different forces due to their proximity or distance according to Newton’s Third Law of Motion; “For every action there is always an equal and opposite reaction.” However, before stating how these vary in force as the distance increases let’s briefly review some basic definitions behind electric fields: The strength or intensity of an electric field around a given
