Two identical spheres, A and B, carry charges of +6 microcoulombs and -2 microcoulombs. If these spheres touch, what will be the resulting charge on sphere A?
+2 microcoulombs
Well, when Sphere A and B touch, they'll have a "shocking" encounter! Since Sphere A has a charge of +6 microcoulombs and Sphere B has a charge of -2 microcoulombs, there will be a "charge transfer party" going on! The charge may flow from the positively charged Sphere A to the negatively charged Sphere B until they achieve equilibrium, resulting in a charge redistribution. Therefore, Sphere A might lose some of its positive charge to Sphere B, leaving Sphere A with a lower charge than before. The precise charge on Sphere A after the shocking encounter would depend on the magnitude of the charge transfer. So, hold on to your circuits to see how much Sphere A ends up with!
When two spheres touch each other, they can transfer charge through a process called charging by conduction. The charges will redistribute until they reach equilibrium.
In this case, sphere A has a charge of +6 microcoulombs, and sphere B has a charge of -2 microcoulombs. Since both spheres are identical, they will have the same amount of charge after they touch.
To find the resulting charge on sphere A, we can calculate the total charge by adding the charges of spheres A and B:
+6 microcoulombs + (-2 microcoulombs) = +4 microcoulombs.
Therefore, the resulting charge on sphere A after they touch will be +4 microcoulombs.
To determine the resulting charge on sphere A when the two spheres touch, we need to consider the principle of charge conservation. According to this principle, the total charge before and after the touching must remain the same.
Initially, sphere A has a charge of +6 microcoulombs (+6 μC), and sphere B has a charge of -2 microcoulombs (-2 μC). When they come into contact, some charge will transfer between the spheres, but the total charge will remain constant.
The charges will redistribute based on the principle of charge equilibrium. Since the spheres are identical, the charge will distribute equally between them.
Let's go through the steps to find the resulting charge on sphere A:
1. Find the total charge before the spheres touch:
Total charge = Charge of sphere A + Charge of sphere B
Total charge = +6 μC + (-2 μC) = +4 μC
2. Divide the total charge equally between the spheres:
Charge per sphere = Total charge / 2
Charge per sphere = +4 μC / 2 = +2 μC
3. Therefore, the resulting charge on sphere A after they touch is +2 microcoulombs (+2 μC).
Keep in mind that when two charged objects touch, electrons can move between them to equalize the charge. In this case, since sphere A had a higher positive charge and sphere B had a lower negative charge, some electrons will move from sphere A to sphere B.
