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 > ERegion B : V < ERegion C : K > ERegion D : V > KState with reason in each case whether a particle can be found in the given region or not. |

Answer» Region A : No, V > E ⇒ E = V + K, K = E – V ⇒ V > E, so K < 0 as KE will become negative. Region B : Yes, V < E, K = E – V, K > 0, total energy can be greater than PE for non zero K.E. Region C : Yes, K > 0, V = E – K, V < 0, KE can be greater than total energy if its PE is negative. Region D : Yes, V > K, K = E – V as PE can be greater than KE. |
