The conductor, which is fixed in place, has radius R = 0.55 m and surface charge density o = +12 nC/m². If the helium nucleus is initially very far away from the conductor, then what initial speed must it be given so that it just barely avoids touching the surface of the conductor before being repelled back to infinity?
