hi tiny-tim! [SIZE="1"]thanks for the tips! :D Ok, basically my physics exam on particle dynamics in electric fields is next week and my teacher told us to remember that sinθ/cosθ=tanθ (something which we btw never used in class) now i understand (you're right) that the horizontal...

Homework Statement So if an electron enters an electric field (between two charged parallel plates) at an angle (i.e not parallel to the x axis) and knowing that the speed is, say, 5 x 10^6 m/s, how would you find the HORIZONTAL velocity of the electron? you know that horizontaly it must...

Absoloutely, sorry my mistake that is the right speed. Yes, sorry again, the plates are 0.1 metres in length and the fluorescent screen is 30mm away. Can you help?

Hey, just need help with something here. Say an electron is traveling in a narrow beam (from an electron gun) at a steady speed of 5X10^-7 m/s. They're directed into the space between two oppositely charged parallel plates 50mm apart and the p.d. on the plates is 2500V. A fluorescent...
