1. The problem statement, all variables and given/known data Find equations of motion (eom) of a particle moving in a D-dimensional flat space with the following Lagrangian L = (1/2)mv2i - k/ra, r = root(x2i), m,k,a are constants 2. Relevant equations 3. The attempt at a solution The equations of motion are given by d/dt(∂L/∂vi) - ∂L/∂xi = 0 So, when I work all this out I get ma = ka/xia+1 I have a feeling this isn;t correct though. Am I doing the partials wrong?
