Social ScienceParticle on a Helical Wire A smooth wire is bent into the shape of a helix5.with cylindrical polar coordinates p= R and : = dó, where R and A are constants andthe z axis is vertically up (and gravity vertically down). Using z as your generalizedcoordinate, write down the Lagrangian for a bead of mass m threaded on the wire. Findthe Lagrange equation and hence the bead's vertical acceleration . In the limit thatR 0, what is 2? Does this make sense?
