A) \[{{R}_{0}}>{{R}_{u}}>{{R}_{d}}\]
B) \[{{R}_{u}}>{{R}_{0}}>{{R}_{d}}\]
C) \[{{R}_{d}}>{{R}_{0}}>{{R}_{u}}\]
D) \[{{R}_{u}}>{{R}_{d}}>{{R}_{0}}\]
Correct Answer: B
Solution :
Rate of flow will be more when lift will move in upward direction with some acceleration because the net downward pull will be more and vice-versa. \[{{F}_{\text{upward}}}=m\,(g+a)\] and \[{{F}_{\text{downward}}}=m\,(g-a)\]You need to login to perform this action.
