You Ve Been Assigned The Task Of Measuring The Speed Of Protons As They Emerge From A Small Accelerator To Do So You D 1 (26.88 KiB) Viewed 43 times

You've been assigned the task of measuring the speed of protons as they emerge from a small accelerator. To do so, you decide to measure how much voltage is needed across a parallel-plate capacitor to stop the protons. The capacitor you choose has a 2.0 mm plate separation and a small hole in one plate that you shoot the protons through. By filling the space between the plates with a low-density gas, you can see (with a microscope) a slight glow from the region where the protons collide with and excite the gas molecules. The width of the glow tells you how far the protons travel before being stopped and reversing direction. Varying the voltage across the capacitor gives the following data: AVC Voltage (V) Glow width (mm) 2 1000 1.7 Alec A 13 - 1500 Ky+gV = K₁+qV₁. LI 1750 10 2000 0.8
