Charges of +3 µC and –5 µC are 2 mm from each other. The –5 µC charge is replaced with a +5 µC charge.

How will the electrical force between the charges compare with the original force?

same force, but in the opposite direction
same force, but in the same direction
greater force, but in the opposite direction
greater force, but in the same direction

Same force, but in the opposite direction.

Reason: Coulomb's law gives magnitude F = k|q1 q2|/r^2, which is unchanged (3 μC × 5 μC). Changing the sign of one charge reverses the force direction (attraction → repulsion).
