Consider a one - dimensional motion a 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 ahead :
State with reason in each case whether a particle can be found in the given region or not .

Explanation

Since total energy `E = K+V`
In region A , `V lt E ` , will be negative which is meaningless .
So particle cannot be found in region A .
In region B , `V lt E ` , K will be positive , so particle can be found in region B .
In region C , `K gt E ` , V will be negative which is possible so the particle can be found inregion C .
In region D , `V gt K , ` E will be positive , so particle can be found in region D .
