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 9.8 m/s^2. if the mass of the pendulum is 0.01kg, what is the force of pulling on the pendulum when it makes a 22.5 degree angle with the vertical?
a. sqrt2-sqrt2/2 n
b.0.049sqrt-sqrt2n
c. sqrt2-sqrt2/2 n
d.0.049sqrt2-sqrt2/2 n
