Why was the period determined with the ball in the pendulum? Equation 14.11 appears to be independent of mass. Explain.
a. The mass of the ball influences the gravitational force acting on it.
b. The period of a pendulum is affected by the density of the material in the ball.
c. The mass cancels out in the equations, making it independent of mass.
d. The period is directly proportional to the square root of the mass.
