Homework Statement
7. A particle of mass m moves (in the region x > 0) under a force F =
−kx+c/x, where k and c are positive constants. Find the corresponding
potential energy function. Determine the position of equilibrium, and
the frequency of small oscillations about it.
Homework Equations
dx/dt = [(2/m)(E - V(x)]^1/2
The Attempt at a Solution
dx/[(2/m)(E+ Clnx - (1/2)kx^2]^1/2 = dt
V = -Clnx + (1/2)kx^2]^1/2
i think at equilibrum point V(x) must be zero but then how can i continue? This is en exam question and i must solve it completely correct. Thank you for your answers. (my firt language is not english. Sorry for mistakes.)
