Ok I have a couple questions here.
1. Calculate the speed of a proton and an electron after each particle accelerates from rest through a potential difference of 190V.
I think I got the part of the electron because I randomly came across the energy value of an electron. The equation I'm using is 1/2mv^2 = q(190V)
2. A hydrogen electron orbits its proton in a circular orbit of radius 0.529X10^-10 meters. What is the electric potential due to the proton at the electron's orbit?
V=kq/r right? But where do I find the q??
3. A uniform electric field E=7500 N/C points in the negative x direction. What is the distance between the +14-V and +16-V equipotentials?
I have no idea on this one.
Any help on any of these woulod be greatly appreciated. Thanks a ton in advance.
