An object with charge q = −6.00×10−9 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. If the electric potential at point A is +30.0 V, what is the electric potential at point B? What is the magnitude of the electric field? What is the direction of the electric field?
