1. The problem statement, all variables and given/known data A classical particle with total energy E moves under the influence of a potential V(x,y) = 3x3+2x2y+2xy2+y3. What is the average potential energy, calculated over a long time? 2. Relevant equations 3. The attempt at a solution I think that this can be solved using Virial Theorem but I am unable to apply the standard form 2T = nV. What is the value of n here?
