Questions & Step-by-Step Solutions
Two identical metal spheres carry charges of +5μC and -5μC respectively. If they are brought into contact and then separated, what will be the charge on each sphere?
Correct Answer: 0μC
Step 1: Identify the charges on the two metal spheres. One sphere has a charge of +5μC and the other has -5μC.
Step 2: When the two spheres are brought into contact, the charges will redistribute between them.
Step 3: Calculate the total charge by adding the charges of both spheres: +5μC + (-5μC) = 0μC.
Step 4: Since the spheres are identical, the total charge (0μC) will be equally distributed between the two spheres.
Step 5: Divide the total charge by 2 to find the charge on each sphere: 0μC / 2 = 0μC.
Step 6: After separating the spheres, each sphere will have a charge of 0μC.
