- The elements in the Periodic Table are arranged into three main groups. Name the group that
each of the elements in the photographs (and
named below) belongs to.
a) Copper
b) Carbon
c) Silicon​

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,?
