(a) A proton is released from rest and accelerates freely through a potential difference* of size 140 V. (*Note: You do not need to know the initial and final voltage values, only their difference!) It will seek a --Select--- potential energy by seeking a ---Select--- so its AV will be: ---Select--- voltage Also, what is its final speed? (b) Repeat part a, but with an electron. It will seek a ---Select--- by seeking a ---Select--- so its AV will be: ---Select--- m/s potential energy voltage Also, what is its final speed? m/s (c) Which particle gained more speed? ---Select--- Which particle gained more kinetic energy? ---Select---
