Q. Which of the following graphs show variation of potential energy (U) with position x.
A) [image:6_image13.emf]
B) [image:6_image14.emf]
C) [image:6_image15.emf]
D) [image:6_image16.emf]
Explanation
(c) The variation of potential energy(U)
With distance(x)is
$\ \ \ \ \ \ \ \ \ \ \ \ \ \ U = \frac{1}{2}kx^{2}$
Hence, parabolic graph is obtained.
