PHYSICS 6B Ch.18 Worksheet clas.ucsb.edu/staff/vince/ 1) In a certain region of space the electric potential V is known to be constant. Is the electric field in this region (a) positive, (b) zero, or (c) negative? 2) Find the change in electric potential energy as charges of (a) 2.2 x 10 -6 C and (b) -1.1 x 10 -6 C moves from a point A to a point B, given that the change in electric potential between these points is ∆V = V B -V A = 24 V. 3) A particle with mass m=1.75 x 10 -5 kg and charge q = 3.20 x 10 -6 C initially passes through point A, moving toward point B at speed 5.00 m/s. ∆V = V B -V A = 60.0 volts. What is the speed of the particle at point B? 4) A +1.2 μC charge and a -1.2 μC charge are placed at positions (0.5m,0) and (-0.5m,0), as shown in the figure. At which of the points A, B, C, or D is the electric potential smallest in value? At which of these points does it have its greatest value? Calculate the electric potential at points A, B, C, and D.
