Problem
A mass connected to a string forms a simple pendulum. The mass is released from rest and undergoes simple harmonic motion. Which one of the following choices correctly ranks the magnitude of the tension in the string (T), the gravitational force on the mass (W), and the net force acting on the mass (F) when the mass swings through its lowest point?
(A) F<W=T
(B) W<T<F
(C) W<F=T
(D) F<W<T
(E) More information is required to answer the question.
