Question:

If the total energy of the particle is E, it will perform periodic motion only if E > 0, E < 0, V0 > E > 0, or E > V0?

E>0

E>V0

E<0

V0>E>0

Solution:

For periodic motion in the given potential the total energy should be less than the maximum potential energy that is E < V0. But also since it is energy of a particle it should be more than zero E > 0. Therefore, option D (V0 > E > 0).
