Question

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

Answer 1

A) same force, but in the opposite direction

Step-by-step explanation:

he's right

Answer 2

Answer: same force in opposite direction.

Explanation: Charges of opposite sign attracts each other and charges with same sign repel each other. Because only sign of negative charge changes, and absolute value of charge remains same, value of force is same but is in opposite direction.
