Questions
A particle of mass m is moving in a field. The potential energy vs position (x ) graph is given as shown in the diagram. The dotted horizontal line represents the total mechanical energy of the particle. Find in which region the particle will not exist?
detailed solution
Correct option is A
We know that K + U = E. And we also know that kinetic energy of a particle can not be negative. In region 1U > E , so kinetic energy will be negative. This is a practical impossibility.Similar Questions
