The graph shows the behaviour of a length of wire in the region for which the substance obeys Hooke's law. P and Q represent
A
applied force, 
extension B
extension, 
applied force C
extension, 
stored elastic energy D
stored elastic energy, 
extension
Text Solution
Verified by ExpertsThe correct answer is:
C
Graph between applied force and extension will be straight line because in elastic range.
Applied force 
Extension
But the graph given is parabolic in nature, so it will be between extension and stored elastic energy.
As, 
or 
or 
as given in graph.
