A 1.00 (m) metal bar that has a mass of 0.490 (kg) is initially pinned in place on an incline 65.0 above the horizontal plane. There is a 0.850 (T) magnetic field directed upward in the region around the bar, and metal contacts along the incline allow a current through the bar from D to C. The coefficient of static friction between bar and contacts is 0.2. What is the minimum magnitude of the current that must pass through the bar to keep it from moving once it is released?

(a) calculate the number of electrons in a small, electrically neutral silver pin that has a mass of 10.0 g. silver has 47 electrons per atom, and its molar mass is 107.87 g/mol. (b) imagine adding electrons to the pin until the negative charge has the very large value 1.00 mc. how many electrons are added for every 109 electrons already present
