हिन्दीRefer to the potential energy function shown in the graph below where a particle of total mechanical energy \( E \) moves along the x-axis. In which of the following regions can the particle NOT physically exist?
Correct answer · Option C
\( x > a \)
Explanation
A particle cannot exist where \( E < V(x) \) because its kinetic energy \( K = E - V(x) \) would become negative. In the graph for \( x > a \), \( V(x) = V_0 > E \), so the region \( x > a \) is classically forbidden.
