When two objects have opposite electric charges they ____
A
attract
B
repel
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -If a positive charge and a negative charge interact, their forces act in the same direction, from the positive to the negative charge. As a result opposite charges attract each other: The electric field and resulting forces produced by two electrical charges of opposite polarity. The two charges attract each other.

Detailed explanation-2: -Opposite charges attract each other, while like charges repulse each other. When two negatively charged objects are brought near each other, a repulsive force is produced. When two positively charged objects are brought near each other, a similar repulsive force is produced.

Detailed explanation-3: -Opposite electric charges attract each other while like electric charges repel each other. This force of attraction and repulsion is called electric forces. Coulombs law states that force of attraction = coulomb’s law constant x charge 1 x charge 2 / (distance between charges)^2. electric force Coulomb’s Law.

Detailed explanation-4: -This “separation of charge” is the reason for the collection of effects we call static electricity. If two objects have different charges, they attract (or pull towards) each other. If two objects have the same charge, they repel (or push away) from each other.
