Direction: Read, analyze and solve the following word problems. 1. How much charge is produced by 5 electrons? 2. How much electron is required to produce a 5-coulomb charge? 3. Calculate the force of attraction between a 1.60 x 10-19 charge and a -2.09 x 10-18 C charge if they are 4.01 x 10-10 m apart. 4. Three charges (+5 microcoulomb, +4 microcoulomb and -9 microcoulomb) are placed at the vertices of an equilateral triangle with a side measuring 15 cm. How much force acts on the -9 microcoulomb charge due to the other two charges? 5. A small sphere with a charge of -0.60 microcoulomb is placed in a uniform electric field of magnitude 1.2 x 106 N/C pointing to the west. What is the magnitude and direction of the electric field
