Question 1

An alpha particle (a helium nucleus, having charge +2e and mass 6.64 × 10-27 kg) moves head-on at a fixed gold nucleus (having charge +79e).  If the distance of closest approach is 2.0 × 10-10 m, what was the speed of the alpha particle when it was very far away from the gold?  (k = 1/4πε0 ,
◦ 2.3 × 106 m/s
◦ 4.6 × 106 m/s
◦ 4.6 × 105 m/s
◦ 2.3 × 105 m/s

Question 2

An electric dipole with ±5.0 μC point charges is positioned so that the positive charge is to the right of the origin and the negative charge is at the origin. How much work does it take to bring a point charge from very far away to the point x = 3.0 mm, y = 0.0 mm? (k = 1/4πε0 = 9.0 × 109 N ∙ m2/C2)
