A block of metal of density 3000 kg/m3 is 2m high and stands on a square base of side 0.5 m. Calculate: 1.The area of the base of the block
2.The volume of the block
3.Mass of the block
4.Weight of the block
5.The pressure exerted by the block

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,?
