Questions & Step-by-Step Solutions
Two identical spheres, one charged positively and the other negatively, are brought into contact and then separated. What will be the charge on each sphere after separation?
Correct Answer: Zero charge on both spheres
Step 1: Start with two identical spheres. One sphere has a positive charge and the other has a negative charge.
Step 2: Bring the two spheres into contact. This means they touch each other.
Step 3: When they touch, the charges can move between the two spheres. They will share their charges equally.
Step 4: After they touch, the total charge is the sum of the positive and negative charges. Since one is positive and the other is negative, they will balance each other out.
Step 5: After separating the spheres, each sphere will have the same amount of charge, which will be neutral (zero charge) because the positive and negative charges cancel each other out.
