Aheavy steel ball is hung from a cord to make a pendulum. the ball is pulled to the side so that the cord makes a 5 ∘ angle with the vertical. holding the ball in place takes a force of 40 n . if the ball is pulled farther to the side so that the cord makes a 10 ∘ angle, what force is required to hold the ball?
