Alarge pendulum with a 200-lb gold plated bob 12 inches in diameter is on display in the lobby of the united nations building. the pendulum has a length of 75 ft. it is used to show the rotation of the earth—for this reason it is referred to as a foucault pendulum. part a) if the pendulum were to be taken to the moon, where the acceleration of gravity is g/6, would the period increase, decrease, or stay the same?

part b) check your result in part a by calculating the period of the pendulum on the moon.

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
