Step-by-Step Solution:
Step 1 of 3

Physics 1120 – Electricity and Magnetism Coulomb’s Law (Study Guide 1 Objective 1)  Fundamentals  Coulomb’s Law  Point Charges and Vectors Bold Text = Formulas Italic Text = Key words or phrases Fundamentals  There are 4 main fundamental forces in the universe – o The Strong Force o The Weak Force o Electromagnetic Force o Gravity  Protons are positively charged  Electrons are negatively charged  Neutrons have no charge Coulomb’s Law  Like charges repel each other, while opposite charges attract each other  Coulomb’s Law states that F = (k*1 *2 )/d^2, where o F = The electric force (in Newtons) o K = Coulomb’s Law Constant, equal to 9
