Please answer this two problems, and kindly show your complete solution.1. A positive charge of 3.6 x 10-5 C and a negative charge of 2.4 x 10-5 C are 0.034 m apart. What is the force between the two particles? 2. Two objects exert a force of 3.7 N on each other. The distance between the objects is 0.32 m. The charge on one object is 2.4 x 10-9 C. What is the charge on the second object? Check the picture for the guide (Coulomb's Law)

Fl FCTRIC FORCE: COULOMBS'S LAW 1 of 1 In the 1780's. Charles Coulomb conducted a variety of experiments in an attempt to determine the magnitude of electric force between two charged objects. The strength of the attraction or repulsion force is determined by Coulomb's taw 1which states that: The electric force Maureen two charges ta proportional to the product of the two charges and inversely proportional to the square of distance between the charges. In equation form. (charge 1)(charge 2) . = x electric force Coulomb constant (distanIZE)2 (Inez) r2 Felecia-i: = kc kc = 9 x 109M - min:2 This equation is very similar to the equation goveming gravitational forces. Both force lavvs states that the force is inversely proportional to the square of distance between the objects. The St unit of charge is coulomb {C}. One coulomb is relatively large quantity of charge. and it is often more convenient to measure charge in mlcrocoulombe: 1 microcoulomh (p6) = 10'6C (one miltionth of a coulomb) Sample Problem: 1.
