A classical particle has total energy E. The plot of potential energy (U) as a function of distance (r) from the centre of force located at r = 0 is shown in the figure. Which of the regions are forbidden for the particle?
  • a)
    I and II
  • b)
    II and IV
  • c)
    I and IV
  • d)
    I and III

Total energy always less than potential energy da. U=2E ennalle.. so U never falls below E

When particle is at r is equal to zero here potential energy is greater than total energy which is not possible so show the area is forbidden
