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
Options
(a) U(x) > E
(b) U(x) < E
(c) U(x) = E
(d) U(x) <= E
Correct Answer:
U(x) <= E
Explanation:
As the particle is moving in a potentialenergy region.
Kinetic energy >= 0
And, total energy E = K.E. + P.E.
U(x) <= E
