B XX XX A metal rod of mass 10 g and length 8 cm is suspended on two springs as shown above. The springs are stretched by 4 cm from their equilibrium position as the rod hangs motionless. 1. Draw a force diagram of the rod. 2. Write the force equations describing your rod. 3. Calculate spring constant k. Now a 20 A current flows through the rod, causing it to move upward 1.0 cm from its previous position as noted in the first part of the problem. 4. Based on the direction of the magnetic field provided (into the page), state the direction of the current. Justify your answer. 5. Calculate the strength of the magnetic field strength.
