Part D.)
What is the acceleration of the loop when it is completely out
of the magnetic field?
Express your answer with the appropriate units. a = ?
A very 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 = 3.30 T and is perpendicular to the plane of the loop. The loop has dimensions 4.00 cm by 60.0 cm, mass 28.0 g, and resistance R = 7.00×10-3. The loop is initially at rest; then a constant force Fext = 0.180 N is applied to the loop to pull it out of the field (Figure 1). Figure < 1 of 1 X X X X 60.0 cm X X X X X 4.00 cm X X BX X X - Fext
