An object with negative charge q = -8.0 x 10^6 C and mass 2.0 x 10^-6 kg is moving in an electric field. There is no force on the object other than the force exerted by the electric field. At point A the electric potential is VA = +800.0 V and the speed of the object is 80.0 m/s. At point B the electric potential is VB = +1200.0 V.

What is the speed of the object as it moves through point B?
