In this problem, we will go through the famous experiment led by Robert A. Millikan. The charge of electron that he calculated by this experiment is 0.6% off from the currently accepted value, that too due to the imprecise value of viscosity of air known at the time. This experiment demonstrates that the electric charge of the oil droplet is some integer multiple of electron charge - thereby establishing charge quantization as an experimental fact. + Eq mg mg It's a free-body diagram. Here, we depict an oil droplet that is falling downwards due to gravity in an air medium. The droplet experiences an upward force due to air friction. When the two forces are on the droplet balance, the droplet falls steadily with velocity va, Find the friction coefficient k. Given the symbolic expression for the mass of the oil droplet m, acceleration due to gravity g the downward terminal velocity of the droplet va. Give your answer in terms of these variables. Use * to denote product and / to denote a division. So, to group the product of, say, a and b_1 write a*b_1. And to write a ratio of say, c_1 and d write c_1/d. To add the product and ratio write a*b_1 + c_1/d. If there are multiple products in the denominator, you should use brackets e.g.: (b_1 + c1)/ (a_1* d). a) Write the mathematical expression for the friction coefficient k. Now, we negatively charge the oil droplet and place it in between the charged plates. There i voltage V=10.68Volt between the plates and the separation between the plates is d=2.81mn Previously we have seen the droplet was steadily falling downwards. Now, due to the electricfo the droplet, it starts to move upwards, towards the positive plate. Hence, there's a force downv on the droplet due to the air friction, as we can see from the free body diagram above. When a forces act on the droplet balance, the droplet steadily moves upwards. Use the symbolic expression for the mass of the oil droplet m, acceleration due to gravity g, th upward terminal velocity of the droplet vu, the downward terminal velocity of the droplet va potential difference V, separation between the plates d. Give your answer in terms of thes variables. Use * to denote product and / to denote a division. So to group the product of, say, a an write a*b_1. And to write a ratio of say, c_1 and d write c_1/d. To add the product and rat write a*b_1 + c_1/d. b)Write the mathematical expression for charge q.
