A small, positively charged ball is moved close to a large, positively charged ball. Which describes how the small ball likely responds when it is released?
Answer
A
It will move toward the large ball because like charges attract.
B
It will move away from the large ball because like charges attract.
C
It will move toward the large ball because like charges repel.
D
It will move away from the large ball because like charges repel.
Explanation
Both balls have positive charge, and charges with the same sign repel. When released, the small ball will therefore move away from the large ball. Choice C correctly describes both the direction of motion and the reason.
