## Homework Statement

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

## Homework Equations

PE + KE = PE +KE

F = q*v*B

## 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.
