1. The problem statement, all variables and given/known data We have a ramp with some angle theta. The metallic bar sitting on a ramp at height h. Also, we have some weight that attached by a rope to a metallic bar while hanging on the height h. There is a magnetic field with a magnitude B and direction k. M = metallic bar m = weight height is the same for metallic bar and weight 2. Relevant equations PE + KE = PE +KE F = q*v*B 3. The attempt at a solution Mgh + mgh = 0.5MV^2 + mgh(1+1/sin/tetha) Solve for V. Then I am lost because the magnetic field does not do work. Hence the final velocity is not changing due to a presence of a magnetic field.
