Repelling force F=kx. What is the motion equation
The Attempt at a Solution
what I did so far, I found the equation of motion which is equal to x= sqrt(2E/K)Sin(wt+b), I am not sure about my answer.
For the second part it is kind of tricky for me, I know a point where the potential energy has a minimum is called point of stable equilibrium, and a point where the the potential has a maximum is called a point of unstable eqiulibrium. I couldn't really got what I should do for the second part
