In Example 3.8, find Q1 and Q2 in terms of the components of F by considering the work done under suitable small displacements. Check that the same expressions for the Qas follow from the chain rule in the case that F = -?U. A particle of mass m is subject to a force F. Obtain the equations of motion in cylindrical polar coordinates. A particle of unit mass is subject to an inverse-square-law central force where r = |r| and r is the position vector from the origin of an inertial frame. Show that the motion is governed by the Lagrangian Write down the equations of motion in spherical polar
