Two people,each of 70 kg mass,are riding in an elevator.One is standing on the floor.The other is hanging on a rope suspended from the ceiling.Compare the acceleration $\overrightarrow { \mathbf { a } } _ { F }$ of the first person to the acceleration $\overrightarrow { \mathbf { a } } _ { R }$ of the second person.Which statement is correct?
A)They are equal and opposite in direction.
B)They are equal and have the same direction.
C)The acceleration $\overrightarrow { \mathbf { a } } _ { R }$ is greater than $\overrightarrow { \mathbf { a } } _ { F }$ ,but they have the same direction.
D)The acceleration $\overrightarrow { \mathbf { a } } _ { R }$ is greater than $\overrightarrow { \mathbf { a } } _ { F }$ ,but they have opposite directions.
E)The acceleration $\overrightarrow { \mathbf { a } } _ { R }$ is less than $\overrightarrow { \mathbf { a } } _ { F }$ ,but they have the same direction.
