Problem
Three isolated conducting spheres are arranged so that only one pair touches at any given time.
• Sphere X (radius 2R) initially has a charge of +9μC.
• Sphere Y (radius R) is initially neutral.
• Sphere Z (radius 3R) initially has a charge of −2μC.
Step 1: Sphere X touches sphere Y and is then separated.
Step 2: Sphere Y immediately touches sphere Z and is then separated.
Determine the final charge on sphere Z after these two contacts.
