1. Suppose that two charges, each with a charge of +1 C are separated by a distance of 1 m. (a) Will they attract or repel?_ (b) Determine the magnitude of the electrical force between them. (9 x 109 N) 2. Two balloons are charged with an identical quantity and type of charge: -2.50 mC. They are held apart at a separation distance of 8 m. Determine the magnitude of the electrical force of repulsion between them. (878.9 N) 3. Two charged boxes (blue & red) are 4 meters apart from each other. The blue box has a charge of +3.37 x 10*C and is attracting the red box with a force of 626 Newtons. Determine charge of the red box (Remember to indicate if it is positive or negative.) (+3.3 x 10*3 C) 4. A piece of Styrofoam has a charge of -4000 uC and is placed 3.0 m from a piece of salt with a charge of -0.003 C. How much electrostatic force is produced? (12,000 N) 5. If charge A has a magnitude of 3 x 10% C, charge B has a magnitude of -1.5 x 10% C, and they are 0.12 m away from each other, find the electrostatic force (2.8 N) 6. Two identical charges of 3.0 mC have an electric force of 1.0 kN between them. How far apart are the charges? (9.0 m)
