Question

Potential energy at mean position of a particle performing oscillation in mean position is

• A. Negative
• B. Minimum
• C. Maximum
• D. zero

Answer 1

Answer: (D)

zero

Potential energy of particle performing oscillation is given by:
$U=\frac{1}{2}k{x}^2$

where $x$ is the distance of the particle from its mean position of oscillation.
Therefore, at the mean position where $x=0$.

Thus the potential energy will be zero.
