Yeah, my confusion is what to do about the inclined wire.

I'm trying to solve this, but i don't really know how to start this problem. There are two line charges and i must find the E. Field on the center.

It's the same as before, but now, the acceleration is upwards .

This was another question. About your answer, i used ## \mu = \theta + \theta_{e}## and i got the right answer. Which is the same as you said.

Yes. Sorry about that. I'll change.

About that, the hamiltonian formalism gave me the expression for the second order differential equation on ##\theta## . But i get your point, i'll be trying to solve this for a new variable : ##\theta= \theta_{e} + \mu## and solve . Still, i dont'r really like that way.

Just found out that i made this post on introductory physics, perhaps it should be advanced. But, how this could help me find the answer?

Here is an image of the problem: The problem consist in finding the moviment equation for the pendulum using Lagrangian and Hamiltonian equations. I managed to get the equations , which are shown insed the blue box: Using the hamilton equations, i finally got that the equilibrium angle...
