An attracting force occurs between two charged objects when the charges are of unlike signs.
An attracting force occurs between two charged objects when the charges are of unlike signs. This is known as the electrostatic force, and it follows Coulomb's Law which states that the force between two charges is directly proportional to the product of their magnitudes and inversely proportional to the square of the distance between them.
To determine if charges attract or repel each other, you can consider their signs. If the charges have opposite signs (one is positive and the other is negative), they will attract each other. On the other hand, if the charges have the same sign (both positive or both negative), the electrostatic force will be repulsive.
So, in this case, the correct answer is option (a) unlike signs.
