Avery long, rectangular loop of wire can slide without friction on a horizontal surface. initially the loop has part of its area in a region of uniform magnetic field that has magnitude b = 2.9 t and is perpendicular to the plane of the loop. the loop has dimension 4.0 cm by 60 cm, mass 24 g, and resistance r = 5.0 × 10^−3 ω. the loop is initially at rest; then a constance force fext = 0.18 n is apllied to the loop to pull it out of the field. (a) what is the acceleration of the loop when v = 3.00 cm/s? (b) what is the loop’s terminal speed when the acceleration becomes zero?
