Three weights...

Question

Three weights $w, 2 w$ and $3 w$ are connected to identical spring suspended from a rigid horizontal rod. The assembly of the rod and the weights falls freely. The positions of the weight from the rod are such that

Solution

The correct option is D All will be at the same distance
For $w, 2 w$ and $3 w$ apparent weight will be zero because the system is falling freely. So the distances of the weights from the rod will be same.
