One puck is anchored to the surface, while the other is allowed to move freely on an air table. The mass of the sphere and puck together is 0.15 kg and the charge on each sphere is 3.0 x 10" C and 5.0 x 10" C. The two spheres are initially 0.25 m apart. How fast (to 3 decimal places, in m/s) will the sphere be moving when they are 1 m apart? +30 x 10* C +5.0 x 10- C free to move will not move
