# Skill check: Electric charge, field, and electric potential

### Problem

Three identically shaped metal spheres start with charges plus, 1, C, comma, minus, 5, C, comma and 0, C as seen in the diagram below.

The spheres are then taken through the following series of actions. First, the left sphere is touched to the middle sphere, they are then separated and returned to their starting positions. Second, the middle sphere is touched to the right sphere, they are then separated and returned to their starting positions.
What will be the final charge remaining on each sphere (left sphere, middle sphere, right sphere) after all the above steps are taken?
