The electric force between two charged bodies at rest is commonly referred to as electrostatic force or Coulomb force.  Although the law existed prior to 1785, it was published for the first time by French physicist Charles-Augustin de Coulomb, hence the name. Coulomb&#8217;s law was critical to the development of electromagnetism theory, possibly even its starting point, because it allowed for meaningful discussion of the quantity of electric charge. The electrostatic force of attraction or repulsion between two point charges is directly proportional to the product of their magnitudes and inversely proportional to the square of their distance, according to the law.<\/p>\n<p>&nbsp;<\/p>\n<p>K or ke is Coulomb&#8217;s constant  (<span class=\"texhtml\"><i>k<\/i><sub>e<\/sub> \u2248 <span class=\"nowrap\">8.988\u00d710<sup>9<\/sup> N\u22c5m<sup>2<\/sup>\u22c5C<sup>\u22122<\/sup><\/span><\/span>), q1 and q2 are the signed magnitudes of the charges, and r is the distance between the charges.<\/p>\n<p>The force is directed in the direction of the straight line connecting the two charges. The electrostatic force between two charges is repulsive if their signs are the same; if their signs are opposite, the force is attractive. . The law is analogous to Isaac Newton&#8217;s inverse-square law of universal gravitation because it is an inverse-square law, but gravitational forces are always attractive, whereas electrostatic forces can be either attractive or repulsive. Coulomb&#8217;s law can be used to calculate Gauss&#8217; law and vice versa. The two laws are equivalent in the case of a single stationary point charge, expressing the same physical law in different ways.  The law has been thoroughly tested, and observations on a scale ranging from 10<sup>\u221216<\/sup> m  to 10<sup>8<\/sup> m have confirmed its validity.<\/p>\n<p><strong>Join Our Online Courses for JEE: <em><a href=\"https:\/\/infinitylearn.com\/jee-class-12-online-course\" target=\"_blank\" rel=\"noopener\">JEE Class 12 Online Course<\/a> |<a href=\"https:\/\/infinitylearn.com\/jee-class-13-online-course\" target=\"_blank\" rel=\"noopener\"> JEE Dropper Online Course<\/a><\/em><\/strong><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Overview\"><\/span><span style=\"color: #0000ff;\"><strong>Overview<\/strong><\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>According to Coulomb&#8217;s law, the force of attraction or repulsion between two charged bodies is directly proportional to the product of their charges and inversely proportional to the square of their distance. It acts along the line that connects the two charges considered to be point charges. In 1785, a French physicist named Charles Augustin de Coulomb coined the term &#8220;tangible relationship&#8221; to refer to a mathematical relationship between two electrically charged bodies. Coulomb&#8217;s law, also known as Coulomb&#8217;s inverse-square law, is an equation for the force that causes bodies to attract or repel each other.  A coulomb is defined as the charge that repels an equal charge of the same sign with a force of 9\u00d710<sup>9<\/sup> N when the charges are separated by one metre in a vacuum. Coulomb force is a mutual and internal force that is conservative.

Coulomb&#8217;s law, on the other hand, determines the magnitude and sign of an object&#8217;s electric force based on its electric charge rather than its mass. As a result, charge determines how electromagnetism affects the motion of charged objects. A charge is a fundamental property of matter. Every constituent of matter carries an electric charge that can be positive, negative, or zero. For example, electrons are negatively charged, whereas atomic nuclei are positively charged. The bulk matter has an equal amount of positive and negative charges, resulting in a net charge of zero.<\/p>\n<div class=\"card\"><a class=\"btn btn-primary\" href=\"https:\/\/infinitylearn.com\/jee-foundation-course-for-class-10\"><br \/>\n<noscript><img style=\"width: 100%; border-radius: 10px;\" src=\"https:\/\/infinitylearn.com\/surge\/wp-content\/uploads\/2023\/09\/Screenshot-2024-08-28-114053-e1724825703440.jpg\" alt=\"JEE Foundation Class 10 Online Course\" data-eio=\"l\" \/><\/noscript><\/a><a class=\"btn btn-primary\" href=\"https:\/\/infinitylearn.com\/jee-foundation-course-for-class-10\"><img loading=\"lazy\" class=\" lazyloaded alignnone\" style=\"width: 100%; border-radius: 10px;\" src=\"https:\/\/infinitylearn.com\/surge\/wp-content\/uploads\/2023\/09\/Screenshot-2024-08-28-114053-e1724825703440.jpg\" alt=\"jee-foundation-course-for-class-10\" width=\"1201\" height=\"636\" data-src=\"https:\/\/infinitylearn.com\/surge\/wp-content\/uploads\/2023\/09\/Screenshot-2024-08-28-114053-e1724825703440.jpg\" \/><\/a><\/p>\n<h3><span class=\"ez-toc-section\" id=\"JEE_Foundation_Class_for_10\"><\/span>JEE Foundation Class for 10<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: center;\">JEE Foundation Class for 10 enhances critical thinking and problem-solving skills through engaging activities and advanced learning techniques, ensuring academic excellence.<br \/>\n<a class=\"btn btn-primary\" href=\"https:\/\/infinitylearn.com\/jee-foundation-course-for-class-10\"><button><strong>JEE Foundation Class for 10<\/strong><\/button><\/a><\/p>\n<\/div>\n<p>Coulomb defined the electric force as having the following properties for charges at rest: Charges with similar charges repel each other, while charges with dissimilar charges attract each other.
