To solve the problem, we need to determine the resulting charge on sphere A after both spheres touch and then separate. Here’s a step-by-step breakdown of the solution: ### Step 1: Identify Initial Charges - Sphere A has a charge of -50e (where e is the charge of a single electron). - Sphere B has a charge of +20e. ### Step 2: Calculate Total Charge - When the two spheres touch, the total charge is conserved. We can calculate the total charge before they touch: ...
