Consider a one-dimensional motion of a particle with total energy E. There are four regions A, B, C and D in which the relation between potential energy V, kinetic energy (K) and total energy E is as given below:
Region A: V > E
Region B: V < E
Region C: K > E
Region D: V > K
Which of the following regions the particle cannot be found?
Text Solution
Verified by ExpertsA
: Total energy of the particle
= kinetic energy + potential energy
E = K + V or K = E – V
Since kinetic energy can never be negative. The particle cannot be found in the region where its kinetic energy would become negative.
In region A, V > E
k becomes negative in this region. Hence, the particle cannot be found in region A.
