Two small spheres are attached to the ends of a long, light, non-conducting rod 40 mm from each other . A third, “middle” sphere can slide along the rod without friction. Each of the three spheres are non-conducting, have identical masses m, and a positive charge q distributed uniformly on the sphere’s surface. The whole system is placed on a horizontal, frictionless, non-conducting surface. Initially, all three spheres are at rest with the middle sphere located a distance 3d from one end of the rod and a distance d from the other end. Find the maximum speed (v) of the middle sphere after the system is released

A positively charged particle starts at rest 25 cm from a second positively charged particle, which is held stationary throughout the experiment. The first particle is released and accelerates directly away from the second particle. When the first particle has moved 25 cm, it has reached a velocity of 10(2–√)ms−1 . What is the maximum velocity (∈×10 m/s) that the first particle will reach?
