Homework Help: Physics

Posted by Jordie on Tuesday, April 27, 2010 at 1:02pm.

an electron is launched at a 30 degree angle with respect to the horizontal and a speed of 3.0*10^6 m/s from the positive plate of the parallel plate capacitor. THe plats of the capacitor are oriented horizontally. The electron lands 5 cm away from the point of release.

a) what is the electric field strength inside the capacitor?

would i use E=(1/4*pi*Eo)(q/r^2)

where q=e and r=5cm

b) what is the minimum separation between the plates?

very confused. any help would be great
