2. The force of repulsion between two identical positive charges is 0.800 N when the charges are 0.100 m apart. Find the value of each charge.
3. A charge of +3.0 x 10–6C exerts a force of 940 N on a charge of +6.0 x 10–6C. How far apart are the charges?
4. A charge of –3.0 x 10–8 C exerts a force of 0.045 N on a charge of +5.0 x 10–7C. How far apart are the charges?
5. When a –9.0-µC charge is placed 0.12 cm from a charge q in a vacuum, the force between the two charges is 850 N. What is the value of q?
6. How far apart are two identical charges of +6.00µC if the force between them is 25.0 N?
