Question

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.

Express your answer with the appropriate units.

Part A:If the electric potential at point A is +30.0 V, what is the electric potential at point B? V_B=__

Part B:What is the magnitude of the electric field? E=__
