PLEASE HELP FAST!!!! As a pendulum swings , the angle (theta) that it makes with the vertical changes through its swing. The force of gravity pulling on the bob is given by F=mg sin (theta), where g is equal to 9.8m/s^2. If the mass of the pendulum is 0.01 kg, what is the force pulling on the pendulum when it makes a 22.5 degree angle with the vertical?

Question
Answer:
The force of gravity pulling on the bob is given by F = mgsinθ
Where m is the mass of the pendulum, g is the gravity, while θ is the angle between the pendulum and the vertical.
Therefore, m = 0.01 kg, g = 9.8 m/s² and θ = 22.5
Force = 0.01 × 9.8× sin 22.5
          = 0.098 × sin 22.5
          = 0.0375 Newtons.
