A particle moves with uniform velocity. Which of the following statements about the motion of the particle is true?

Three identical particles are located at the vertices of an equilateral triangle. Each particle moves along a meridian with equal speed towards the centroid and collides inelastically. (a) all the three particles will bounce back along the meridians with lesser speed. (b) all the three particles will become stationary. (c) all the particles will continue to move in their original directions but with lesser speed (d) nothing can be said

According to Newton's law of gravitation each particle attracts every other particle. But we do not see bodies on the surface of the earth moving towards each other. Why?

This question contains Statement-1 and Statement-2. Of the four choices given after the statements, choose the one that best describes the two statements. Statement-1: For a charged particle moving from point P to point Q, the net work done by an electrostatic field on the particle is independent of the path connecting point P to point Q. Statement-2: The net work done by a conservative force on an object moving along a closed loop is zero.
