Two charges \( q_1 = 2 \, \mu \mathrm{C} \) and \( q_2 = -3 \, \mu \mathrm{C} \) are placed 10 cm apart in a vacuum. What is the magnitude and direction of the force between them?
Show Hint
In Coulomb’s law, the force is attractive when the charges are of opposite signs and repulsive when the charges are of the same sign. Always convert the distance to meters in SI units for proper calculation.
