Question: An object with charge q = -6.00 10 -9 C is placed in a region of uniform electric field and is released from rest

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 3.00 × 10^-7 J.

(a) If the electric potential at point A is +30.0 V, what is the electric potential at point B?

(b) What are the magnitude and direction of the electric field?
