Electrostatics Sample Problems
- A +6 mC and a +3 mC charge are separated by 0.03 m. What is the magnitude and the direction of the electrostatic force between them?
- A repulsive force of 220 N exists between an unknown charge and a charge of +4.7 mC. If they are separated by 2.5 cm, what is the magnitude and sign of the unknown charge?
- Two protons are separated by 1 x 10-11 m. What is the magnitude of the electrostatic force between them?
- A +4 mC charge lies 2 m to the left of a -5 mC charge. A -6 mC charge lies 4 m to its right. What is the magnitude and the direction of the resultant force on the center charge?
- In number four, what is the magnitude and direction of the resultant force on the +4 mC charge?
- Three charges form a right triangle. A -3 mC charge is 4 cm above a +6 mC charge. A +1.5 mC charge is 3 cm to the right of the +6 mC charge. What is the magnitude and direction of the resultant force on the +6 mC charge?
- Now find the resultant force on the +1.5 mC charge.
