Two charges, +5C and +5C, are 2 meters apart. Calculate the force between them. How would the force change if one charge became -5C?
💡 Hint: Apply Coulomb’s Law and consider the sign change for charges.
In a system with three charges positioned as follows: Charge A is +3C at (0,0), Charge B is +2C at (3,0), and Charge C is -1C at (3,4). Calculate the net force on Charge A.
💡 Hint: Break it down into two parts: Forces from B and C acting on A.
