Answer to Question #223303 in Astronomy | Astrophysics for Haddensen

Question

At the instant the bob of an oscillating pendulum reaches the equilibrium position, the displacement is zero. Which of the following statements correctly describes the kinetic energy of the bob and the tension in the thread from which it is hanging at zero displacement?

A. Zero k.e and max tension

B. Max k.e and max tension

C. Max k.e and min tension

D. Zero K.e and Min tension

Answer 1

At the equilibrium position the kinetic energy of the pendulum bob is maximum and the tension in the thread is minimum. Therefore, the correct answer is (C).

Answer:

C. Max k.e and min tension
