Question 1:

E Bo A . In the figure shown above, points A and B are 6 cm apart along the lines of a uniform field E = 650i V/m. a) Find the change in potential VB - VA: b) What is the change in potential energy UB - UA as a point charge q = -2 /C is moved fromA to B?What potential difference (take the absolute value) is needed to accelerate the following particles from rest to 0.05 c, where c is the speed of light? a) a particle with a charge 2 e and a mass 8 u? b) a particle with a charge 96 e and a mass 225 u?C b a A A 8 C point charge is placed at the origin as shown in the figure above, where a = 1.6 cm, b = 3 cm c = 1.6 cm and d = 2.7 cm. Find the potential at the points A, B and C: VA VB V Vc
