a) Explain what happens inside a dielectric material at the molecular level in the presence of an external electric field E, b) When studying electrostatics we come to the conclusion that in equilibrium there is no electric field inside a conductor. How is it that now that there is an electric current inside the conductor, one can already speak of...

An object with charge q = −4.00×10−9 C is placed in a region of uniform electric field and is released from rest at point A. After the charge has moved to point B, 0.500 m to the right, it has kinetic energy 5.00×10−7 J . A)If the electric potential at point A is +30.0 V, what is the electric potential...

(c) An electric dipole consists of 1.0 g spheres charged to +3.0nC at the ends of a 15 cm long non-conducting rod of mass 4g (don't try to look up "electric dipole", it won't help you. For the sake of this problem, it's just a fancy word for what I just described). The dipole rotates on a frictionless pivot at...
