In a closed system, two neutral objects are brought into contact with each other. After the contact, we find that the first object has a positive charge. What can we now conclude about the second object?
The second object is still neutral.
The second object has a positive charge with the same magnitude as the charge on the first object.
The second object has a negative charge with a magnitude equal to the magnitude of the positive charge on the first object.
The second object has a negative charge with a magnitude less than the magnitude of the positive charge on the first object.
The second object has a negative charge with a magnitude equal to the magnitude of the positive charge on the first object.
This is because charge is conserved in a closed system, meaning that the total charge remains the same before and after any interaction. Since the first object gained a positive charge, the second object must have gained an equal and opposite negative charge to ensure that the total charge in the system remains zero.
