1. A 4.49 X 10'3 C charge is separated from a 1.15 X 109 C charge by a distance of 2.01 X 105'\" m. Determine the repulsive force between the two charges. 2. There are two steel balls both weighing 0.75 kg and carrying equal but opposite charges. Find their individual charges if the force of attraction between them is 5.11 N and if they are separated by a distance of 1.11 In. 3. Two charges (2.09 x 10'\" C and +1.60 X 10*19 C) are separated by a distance of 4.01 X 10-10111. Compute the force of attraction between them
