일반물리학 2 — Electric Fields: Problem 27

27 Beams of high-speed protons can be produced in “guns” using electric fields to accelerate the protons. (a) What acceleration would a proton experience if the gun’s electric field were \( 2.00 \times 10^4 \text{ N/C} \)? (b) What speed would the proton attain if the field accelerated the proton through a distance of \( 1.00 \text{ cm} \)? (c) How much time would be required?
