A 1.50 x 10'14 kg oil drop accelerates downwards at a rate of 1.80 mls2 when placed between two horizontal plates that are 9.40 cm apart. The potential difference between the two plates is 930 V. Determine the magnitude of the charge on the oil drop. Show all your work... 0 lo: 1.80 ml's.2 . According to Maxwell's Laws of electromagnetism, the orbital frequency (the number of complete orbits per second) of an electron will match the frequency of the emitted radiation. a. As an electron spirals into the nucleus its orbital radius would decrease and its speed would increase. How will those changes affect the electron's orbital frequency?!u b. If an electron spirals into the nucleus, what would happen to the frequency of the emitted radiation? c. If an electron spirals into the nucleus its orbital radius would decrease and its speed would increase. What type of spectrum would be produced
