oh ok yh thanks :)

yeah i get your last sentence but i thought the acceleration increased and that it wasn't constant.

electric force.i think that's what its called?

probably the +ve plate attracting the electron

i don't think you have enough info because to calculate the vf you need the horizontal velocity vx.you use Pythagoras to find the vf. vx^2 + voy^2 gives you vf and you find the angle using tan\theta = voy/vx i got the same voy as you but i don't think that how u calc vf. i was taught this way...

okay i did make an attempt but I am not really sure about the principles i need to apply. i think only the direction changes but not the speed. but I am not sure why or if its true.

Homework Statement a cathode ray tube contains parallel plates that are 30mm long and have an electric field strenght between them of 2.5x10^4. an electron traveling at 2.9x10^7m/s enters the field at right angles. explain why the electron experiences a change in velocity.Homework Equations The...
