Q. Three weights $W,\ 2W$ and $3W$ are connected to identical springs suspended from a rigid horizontal rod. The assembly of the rod and the weights fall freely. The positions of the weights 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 $W,\ 2W,\ 3W$ apparent weight will be zero because the system is falling freely. So the distances of the weight from the rod will be same
