Statement-1: Graph between potential energy of spring versus the extension or comparision of the spring is a straight line.
Statement-2: Potential energy of a stretched or compressed spring is proportional to square of extension or comparission.

A

Statement-1 is true, Statement-2: is true, Statement-2 is a correct explanation for Statement-1.

B

Statement-1 is true, Statement-2: is true, Statement-2 is NOT a correct explanation for Statement-1.

C

Statement-1 is true, Statement-2 is false

D

Statement-1 is false, Statement-2 is true

Text Solution

Verified by Experts

The correct Answer is:
D
Potential energy of spring is directly proportional to squre of extension or compression in the spring. So graph will be parabola.
