Question : 20

Total: 60

A particle of unit mass is moving along the x-axis under the influence of a force and its total energy is conserved.Four possible forms of the potential energy of the particle are given in column I(a and U0 are constants).Match the potential energies i column I to the corresponding statement(s) in column II.

The force acting on the particle is zero at x=a

The force acting on the particle is zero at x=0

The force acting on the particle is zero at x=−a

The particle experiences an attractive force towardsx=0in the region |x|<a

The particle with the total energy

can oscillate about the point x=−a
