Question: A uniform bar has mass 0 . 0 1 4 0 kg and is 3 0 . 0 cm long. It pivots without friction about

A uniform bar has mass 0.0140 kg and is 30.0 cm long. It pivots without friction about an axis perpendicular to the bar at point \( a \) in (Figure 1). The gravitational force on the bar acts in the \(-y \)-direction. The bar is in a uniform magnetic field that is directed into the page and has magnitude 0.200 B .
