How fast is the bar moving

Reference no: EM13657195

Assume the light bulb in Figure 22.4b is replaced by a6.0Ω electric heater that consumes 15 W of power. The conducting bar moves to the right at a constant speed, the field strength is 2.4 T, and the length of the bar between the rails is1.2m.

1. How fast is the bar moving?

2. What force should be applied to the bar to keep it moving to the right at the constant speed found in part (a)?
