Question
- D . A uniform electric field is setup between two 2 cm long conducting plates as shown below. A triply ionized iron atom(that's Fe+ for the chemists in the audience, and a once neutral atom that is novw missing three electrons for the rest of us.) enters the region between the plates at a point midway between the plates(which are separated by 1 cm) with an initial speed of 4 x 105 m/s. The ion, of mass 9 × 10-a kg, strikes the upper plate on its far edge. Assuming that gravity can be ignored, answer the following questions: 9X/ Fe 3. What is the charge, in Coulombs, of the Fe+ ion?(5 points)Explanation / Answer
Fe3+
The 3+ means that Fe3+ has 3 protons more than the number of electrons. Thus,
charge = +3e
= 3 x 1.602 x 10-19 C
= 4.806 x 10-19 C
