← A force F = (y i + 2x j) N, where x and y are the coordinates in metres, acts on a particle. The particle moves from the origin O to the point P (2 m, 2 m) along the parabola y = x²/2, as shown in the figure. How much work does the force do?A uniform rod of mass 2.0 kg and length 1.0 m is hinged at one end to a wall, so that it can turn freely in a vertical plane. It is held horizontal and then released, as shown in the figure. Take g = 10 m/s². Which of the following statements are correct? →
