This question has statement and statement II of the four choices given after the statements choose the one that best describes the two statements
Statement-I In free space a uniform spherical planet of mass M has a smooth narrow tunnel along its diameter. This planet and another superdense small particle of mass M start approaching towards each other from rest under action of their gravitational force. When the particle passes through the centre of the planet sum of kinetic energies of both the bodies is maximum

statement-II When the resultant of all forces acting on a particle or a particle like object is constant in direction the kinetic energy of the particle keeps on increasing.
