Question 1 eV - is the energy, which an particle with elementary charge gets going through 1V voltage. Find relation between energy in eV and JIn a Millikan oil-drop experiment, a particular oil drop weighs 4.37×10^−14 N. The parallel plates are separated by a distance of 1.80 cm.When the potential difference between the plates is 546 V, the drop is suspended. a. What is the net charge on the oil drop? b. If the upper plate is positive, how many excess electrons are on the oil drop?A student is able to isolate a single charged oil drop while performing a Millikan oildrop experiment in the physics laboratory. The oil drop, of mass 1.23 x 10-15 kg, is suspended betweentwo horizontal parallel plates spaced 8.0 mm apart when a voltage of 120 V is applied to the platessuch that the lower plate is negative and the upper plate is positive. Does the oil drop have an excess or deficit of electrons? Explain Determine the actual number of excess or deficit electrons on the oil drop What would be the acceleration of the oil drop if the voltage across the plates were tobe increased to 300 V? What would be the acceleration of the oil drop if the voltage across the plates were set to0 V (in other words, the plates are turned off)?

- 2. During the experiment, the lights will be turned down. You will observe the electron beam as a purple green glow. This is caused when a small fraction of the electrons strike some of the very low density of mercury atoms in the residual gas of the partial vacuum. The beam electron knocks one of the atomic electrons into a higher energy orbit momentarily. When it comes back down to its ground state, the colored light is emitted. Why does the beam still seem to go in a circle, if the light only comes when an electron collides with an atom and hence is scattered off in some random direction?The electronic structure of a toms and molecules may be investigated using photo eletrons spectroscopy An electron in is to electron spectro mater Hoy a uniform electric field to a speed of 420kms-1 in 10µs. determine the kinetic energy of the electron Pho accelerated from nes @ 8.0x10-20 Nm 1.6x10-25 N.m 38 x 10-25 N.m d the electronic structune ota toms and maecules may be investigated using photo electron spectroscopy.
