Q1. A 3.10-m-long, 310 kg steel beam extends horizontally from the point where it has been bolted to framework of a new building under construction. A 73.0 kg construction worker stands at the far end of the beam.What is the magnitude of the torque about the point where the beam is bolted into place?

Q2. In the steady state, the current moves straight along the bar, so the net sideways force on a moving charge must be zero. Utilize this fact to establish the drift speed of the mobile charges.
