Answer 1

The only correct statement on that list is choice-C: If a positively charged rod is brought close to a positively charged object, the two objects will repel.

Answer 2

C. If a positively charged rod is brought close to a positively charged object, the two objects will repel.

Step-by-step explanation:

According to coulomb's law, the magnitude of the electric force between two point charges at rest is directly proportional to the product of the magnitude of both charges and inversely proportional to the square of the distance that separates them. This force is repulsive for like charges and attractive for opposite charges.
