Eletrifica-te

Identical charges A, B, and C are located between two oppositely charged parallel plates, as shown in the diagram below. The magnitude of the force exerted on the charges by the electric field between the plates is

• least on A and greatest on C

• the same on A and C, but less on B

• the same for A, B, and C

• greatest on A and least on C
