Statement I: If the lower cord of a hanging block is pulled down very slowly, the upper cord is the one that finally breaks.

Statement II: In a slow pull the upper cord carries the weight of the block plus the applied pull, while the lower cord carries only the pull.

Answer:

Solution:

$T_{u pp er} = m g + F$

and

$T_{l o w er} = F$

in a slow pull, so the upper cord always reaches the breaking tension first.

Both statements are true.

Option A.
