Pleasee help me

45. Two big surface fields are separated 25 mm away from each other, and the space between them is filled with liquid that has absolute viscosity of 0.958. Assuming its velocity gradient is a flat line, what is the force needed to attract a very thin slab whose area is 0.37 m2 vast, in a constant velocity of 0.3 m/s, if the slab is 8.44 mm away from one of the surface?

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,?
