What is the speed of the particle at point B if it moves from point A to point B where the electric potential at point B is greater than the potential at point A? The particle has a charge of -5.50 μC, a mass of 3.00×10−43.00×10 −4 kg, and a speed of 4.40 m/s at point A.
a) 7.65 m/s
b) 8.20 m/s
c) 9.05 m/s
d) 9.50 m/s
