3. A beam of helium-3 atoms (m = 3.016 u) is incident on a target of nitrogen-14 atoms (m = 14.003 u) at rest. Dur- ing the collision, a proton from the helium-3 nucleus passes to the nitrogen nucleus, so that following the col- lision there are two atoms: an atom of "heavy hydro- gen" (deuterium, m = 2.014 u) and an atom of oxygen-15 15.003 u). The incident helium atoms are moving at (m a velocity of 6.346 × 10° m/s. After the collision, the deu- terium atoms are observed to be moving forward (in the same direction as the initial helium atoms) with a velocity of 1.531 x 10' m/s.

Millikan's oil drop experiment in the early 1900s is historically famous, because. a) it discovered the existence of electrons. it provided experimental evidence for the existence of an electron. it revealed that electrons are negatively charged. b) c) d) it estimated the value of the fundamental charge. field is
Coulomb's law describes the force between two charges. We have written it as follows: FE Q-9 = kcqQ roa 2 (1) In various textbooks you will see this written in other ways: for example F=k F1 on 2 22. k992 = (2) (3) A. For the expression (1) explain what each of the terms in the equation means and what they tell you about the electric force between two charges. B. Expressions (2) and (3) differ in various ways from expression (1). Explain some of these differences (at least one for each) saying what information is represented differently (or not represented) compared to (1). What do the vertical bars mean in expression (3)? C. Electric forces satisfy Newton's third law. Explain how this information is coded into expression (1). D. In the problem Analyzing dipoles, we discovered that the force between a single charge and a dipole doesn't behave like 1/r², but falls off like 1/r³ at long distances. Does this mean that Coulomb's law doesn't hold? When can we use it and when can we not use…
