    Work and Bernoulli Eqn in Rotating Frame with Constant Angular Speed

    I think something with mass m is on the disk and since the disk is rotating there is centrifugar force to move that thing from a to b...Does anyone have any idea how to calculate the work? Also how this is related in q.2? josh

    How Do I Approach Potential Energy and Electric Fields in Physics?

    oops... Ok I found out V=-tan^(-1)(x/y)+tan^(-1)(y/x)+C where C is arbirary constants.. And.. now what? should I take a differentiate V as the upper equation says so is that basically asking two equations are commute? ...

    Work and Bernoulli Eqn in Rotating Frame with Constant Angular Speed

    Q 1:Consider a disk of radius R. This disk is rotating around its center with a constarnt angular speed of w. Find the necessary work to move a body of mass m radially with respect to the disk from r=a to r=b. Q 2:The Bernoulli equation for a unit mass can be written as gdz+1/2VdV+vdP=0...
