1) Find the change in electric potential energy as charges of (a) 2.2*10^-6 C and (b) -1.1*10^-6 C moves from a point A to a point B, given that the change in electric potential between these points is deltaV= Vb-Va = 24V.
2) A particle with mass=1.75*10^-5 kg and charge q = 3.20*10^-6 C initially passes through point A, moving toward point B at speed 5.00 m/s. DeltaV = Vb - Va = 60.0V. What is the speed of the particle at point B?
