Question on: JAMB Physics - 2022
The potential energy in an elastic string of force constant k, which has an extension X is?
A
kX
B
KX\(^{2}\)
C
½KX\(^{2}\)
D
½K
Ask EduPadi AI for a detailed answer
Correct Option: C
The potential energy stored in an elastic string is given by the formula:
Potential Energy (PE) = ½ * k * X²
where:
- k is the force constant
- X is the extension of the string
Therefore, the correct answer is ½KX².
