Question

In a pendulum, when the angle is 0∘, the acceleration is directed up, following Newton's 2nd law. Consequently, the net force must be directed:

a) Downward
b) Upward
c) Horizontal
d) None of the above

Answer 1

In a pendulum, when the angle is 0∘, the net force is directed downward due to the force of gravity.

Step-by-step explanation:

In a pendulum, when the angle is 0∘, the acceleration is directed down due to the force of gravity. According to Newton's second law, the net force is in the same direction as the acceleration, so the net force is downward.
