Q. Three weights $w,2w\ and\ 3w$ are connected to identical spring suspended from a rigid horizontal rod. The assembly of the rod and weights fall freely. The positions of the weight from the rod are such that
A) $3w\ $will be farthest
B) $w$ will be farthest
C) All will be at the same distance
D) $2w\ $will be farthest
Explanation
(c) For $w2w,3w$ apparent weight will be zero because the system is falling freely. So the distances of the weights from the rod will be same.
