    What is the maximum speed of a proton if its kinetic energy is 1.28x10^-14 J?

    Oh so do I use V= p.e. / q because the electrical energy has been transferred to kinetic energy during the acceleration?

    What is the maximum speed of a proton if its kinetic energy is 1.28x10^-14 J?

    So first I tried to use KE=1/2 x m x v^2 but then realized I didn’t have the velocity and I can’t figure out a way to obtain it. I then tried to work out the energy using a different equation, W= q x v but that left me with 1.28x10^-14 J which seemed too small. I also then have to calculate the...

    What are the key topics in A-Level Physics?

    Hi! I’m Lily, I’m studying my a levels in physics in the uk. I’d love for people to help me with some of my questions as it is important to understand full topics here in order to answer exam questions to the best I can! Thanks in advance! Lily :)
