Question

assertion: a spring has potential energy , both when it is compressed or stretched.

reason: in compressing or stretching, work is done on the spring against the restoring force.

(1) Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A)
(2) Both assertion (A) and reason (R) are true but reason (R) is not correct explanation of assertion (A)
(3) Assertion (A) is true but reason (R) is false.
(4) Assertion (A) is false but reason (R) is true.

​

Answer 1

Answer:

4

Explanation:

because it can experience only one energy as there are different criteria for kinetic and potential energy.

Answer 2

Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A)

• Because of its placement, potential energy exists. When an object's original position alters, it stores some potential.
• It can also be owing to effort done against other forces that are moving in the opposite direction.
• When the string is stretched, x is negative, and when constricted, x is positive.
• In any instance, spring will attempt to return itself to its former state.
• As a result, this form of energy refers to the work done against its restorative force.
