Hey everyone, I'm 18 and a freshman taking Physics II (electr.). I am in desperate need of help Without exagerating, I have been working on 3 problems for the past hour. If someone could please help me I would appreciate it so much... Here's one of my problems: Book: Cutnell & Johnson Physics 7th Edition pp.569 #38 An electron is released from rest at the negative plate of a parallel plate capacitor. The charge per unit area on each plate is o=1.8 x 10^-7 C/m^2, and the plates are separated by a distance of 1.5 x 10^-2m. How fast is the electron moving just before it reaches the positive plate? My Answer: 1.43 x 10^26 m/s I don't think my answer is accurate. If there was a way to find the initial velocity without first having the final velocity, I think I could figure out one of the others I have. Anyways, Thanks for any help guys!
