Auniform rod ab is of length 180 cm and mass 2 kg. it balances horizontally on asingle support when carrying loads of 1 kg and 3 kg at distances 60 cm and 120 cmfrom a side. find the position of the support and the magnitude ofdownward thrust on it.

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,?
