Work Energy and Power - Result Question 16
18. A particle with total energy $E$ is moving in a potential energy region $U(x)$. Motion of the particle is restricted to the region when
[NEET Kar: 2013]
(a) $U(x)>E$
(b) $U(x)<E$
(c) $U(x)=O$
(d) $U(x) \leq E$
Show Answer
Answer:
Correct Answer: 18. (b)
Solution:
- (b) As the particle is moving in a potential energy region.
$\therefore$ Kinetic energy $>0$
And, total energy $E=$ K.E. + P.E.
$\Rightarrow U(x)<E$
