Answer:
D) not enough information to decide
Explanation:
Data provided in the question
The True weight of book stacks = 165 N
Reading of the scale = 165 N
Constant velocity = 2 m/s upward or downward
Based on the above information
If you moved at a constant velocity the scale interprets the same because of the momentum you've got. The scale will change the number only when acceleration is present.
Therefore in the given situation, the option D is correct as it not have enough information for deciding it
