A particle of mass m is taken along different frictionless paths AB as indicated by the following diagrams. In each case, the particle starts from rest at A and reaches the point B finally. All the paths are in a vertical plane and the external forces act such that the particle moves along the respective paths without restraint;
Which of the following statements will be true in respect of the above motions?

Question

A particle of mass m is taken along different frictionless paths AB as indicated by the following diagrams. In each case, the particle starts from rest at A and reaches the point B finally. All the paths are in a vertical plane and the external forces act such that the particle moves along the respective paths without restraint;

Which of the following statements will be true in respect of the above motions?
