Discuss your experience when standing in front of different types of mirrors in a fun house or even in a clothing store. Why do you look taller or shorter, narrower or wider, or distorted in other ways in these mirrors? Maybe you’ve even seen more than one of yourself in a set of mirrors. Describe your experience. Are these trick mirrors or applications of physics? Explain your answer.

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,?
