1. The problem statement, all variables and given/known data A particle of mass m moves along the positive x-axis with a potential energy given by V(x)=C+4/x^2+x^2 where C is a postive constant. Calulate the equilibrium position X0 of the particle. 2. Relevant equations None. 3. The attempt at a solution I realise that at the equilibruim position x=0. However the C part has thrwon me, am i supposed to integrate or differentiate this??? Thanks.
