Two charges, +3μC and -3μC, are placed 0.2 m apart in a vacuum. Find the electrostatic force between them and specify its nature.
💡 Hint: Carefully consider the signs of the charges.
A charge of +10μC is fixed, and a second charge of unknown magnitude is placed 0.1 m away from it and experiences a force of 0.02 N. What is the magnitude of the second charge?
💡 Hint: You need to isolate the unknown charge in your final formula.
