Two stationary positive point charges, charge 1 of magnitude 3.30 nC and charge 2 of magnitude 1.90 nC, are separated by a distance of 44.0 cm.. An electron is released from rest at the point midway between the two charges, and it moves along the line connecting the two charges. What is the speed Ufinal of the electron when it is 10.0 cm from charge 1? Express your answer in meters per second. ▸ View Available Hint(s) G| ΑΣΦ Ufinal=5.44.106 ? m/s

Consider the arrangement of three point charges in a right triangle shown in the figure, which have charges q1 = 9.5 μC, q2 = -69 μC, and q3 = 25 μC. The distance between q1 and q2 is 28 cm and the distance between q2 and q3 is 61 cm. Previous answers aren't correct. 1. How much potential energy, in joules, is stored in this configuration of charges?  U=? 2. Now assume that q1 and q2 are fixed in space at the locations indicated, and q3 is brought into it's position from infinity. What is the change in potential energy of the system, in joules, during this process?  U3=?

Two equally charged, 1.00 g spheres are placed with 4.00 cm between their centers. 2 When released, each begins to accelerate at 225 m/s . As the spheres move, do you expect the force between them to increase, decrease or remain the same? Use an equation to justify your reasoning. Calculate the spacing needed between the spheres that would cut the force between them in half.
