II. KEY CONCEPT Law of charge states that alike charges repel and unlike charges attract. We have seen that a force acts between two or more charged objects. A French scientist Charles-Augustin de Coulomb formulated Coulomb's Law. This law states that the electric force (attractive and repulsive) is directly proportional to the product of the two charges and inversely proportional to the square of distance between the two charges. In symbols F = k qiq2/R2 Where F is the magnitude of electrical force in newton (N) k is the electrostatic constant equivalent to 9.0 x 10 9 N.m2/C2 al and q2 are the electric charges in coulomb (C ) R is the separation between two charges in meter (m) The direction of the electric force is dependent on the relative signs of the two charges. If the charges have unlike signs, they exert attractive force on each other and if the charges have like signs, they will exert repulsive force on each other.Using the Equation F= k q1 q2/R2, complete the table below. Show your solution.

ANALYSIS 1. What will happen to the electrostatic force if the product of their charges is doubled? 2. What will happen to the electrostatic force if the separation of their distance is tripled? 3. What will happen to the distance if the electrostatic force is doubled? 4. What will happen to the electric charge if the electrostatic force increases four times?VI. GENERALIZATION State the relationship of electrostatic force to electric charge and the distance between the charges. VII. APPLICATION How does Coulomb's Law differ from The Law of Universal Gravitation? VIII. ENRICHMENT ACTIVITY Problem Solving: Solve the problem below. Show your solution. 1.
