Question

Which statement about electric charges is correct?

(A) An object with a positive charge and an object with a negative charge will repel each other.
(B) An object with a negative charge and an object with a positive charge will attract each other.
(C) Two objects with negative charges will attract each other.
(D) Two objects with positive charges will attract each other.

Answer 1

Statement (B) is correct: an object with a negative charge and an object with a positive charge will attract each other. This is because electric charges of opposite signs attract each other, while charges of the same sign repel each other. This is known as Coulomb's law, which describes the interaction between electric charges.
