5. A Foucault pendulum is installed in Saskatoon (latitude 52.1 North) (a) (10 pts) When the pendulum bob is at 10 m off the origin in norther direction (that is, = y 10 m, refer to the diagram in lecture note), calculated the ratio of centrifugal force to the gravitational force applied to the pendulum bob. The earth's angular speed is a 7.27 x 10-5 rad/s. = (b) (10 pts) Calculate the ratio between the magnitude of the inertial force, -mA,, due to the rotation of the origin of the coordinate system fixed on the ground, to that of the gravitational force applied to the pendulum bob.
