A long rectangular loop of wire can slide without friction on a horizontal surface. Initially the loop has post off its area in a region of uniform magnetic field that has magnitude B$=2\mathrm{.}90$T and is perpendicular to the plane of the loop. The loop has dimensions $4$cm by $60$cm$,$ mass of $24$ g and resistance R$=5$x$10^-3.$ The loop is initially at rest then a constant force Fext$=0\mathrm{.}180$N is applied to the loop to pull it out of the field what is the acceleration of the loop when v$=3$m$/$s$?$ What is the loop$$s terminal speed and acceleration when the loop is moving at that terminal speed? What is the acceleration of the loop when it is completely out of the magnetic field?
