Consider the arrangement of three point charges in a right triangle shown in the figure, which have charges q1 = 5.5 μC, q2 = -61 μC, and q3 = 35 μC. The distance between q1 and q2 is 39 cm and the distance between q2 and q3 is 78 cm. Part a How much potential energy, in joules, is stored in this configuration of charges?
s 2 Question 1 In the figure, two identical spheres of radius R are set up a distance d away from each other (d is the distance from the center of one to the center of the other). One sphere has charge +Q and is centered at x -0. The other sphere has a charge-Q and is centered at x = d. You are using this set-up to accelerate a small particle with charge q and mass m. The particle starts at a position x, and ends up at a position x-d-x (The distance from the positive sphere to x, is equal to the distance from x, to the negative sphere.) The values in this problem are: d-5.71 m, R-0.19 m, Q-8.53x106 C. q-9.27x10 C m-1.47x105 kg. x₁-0.54 m If the small charge starts at rest, what is the final speed of the charge when it reaches x,? Give your answer in m/s to at least three digits, to avoid being counted incorrect due to rounding. Note: You can assume that the spheres are far enough apart that the charge on the sphere is uniformly distributed on their surfaces. R,+Q R₁-Q
