Three weights W, 2W and 3W are connected to identical springs suspended form 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
3 W will be farthest
B
W will be farthest
C
All will be at the same distance
D
2 W will be farthest
Answer
All will be at the same distance
Explanation
Solution
For W, 2W, 3W apparent weight will be zero because the system is falling freely. So there will be no extension in any spring i.e. the distances of the weight from the rod will be same.
