Work Energy and Power question

2013 · Q149

NEETPhysicsWork Energy and PowerMCQ+4 / −1
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
  1. A
    U(x) < E
  2. B
    U(x) = 0
  3. C
    U(x) ≤\le≤ E
  4. D
    U(x) > E
View written solutionFree

Correct answer: C

As the particle is moving in a potential energy region.

∴\therefore∴ Kinetic energy ≥\ge≥ 0

And, total energy E = K.E. + P.E.

⇒\Rightarrow⇒ U(x) ≤\le≤ E
