An electron is released from rest at the negative plate of a parallel plate capacitor. the charge per unit area on each plate is = 2.2 × 10^-7 c/m^2, and the plates are separated by a distance of 1.3 × 10^-2 m. how fast is the electron moving just before it reaches the positive plate?

Explanation:

Given

Charge per unit area on each plate()=

Plate separation(y)=0.013 m

and velocity is given by

where a=acceleration is given by

e=charge on electron

E=electric field

m=mass of electron

substituting values

a. is the answer because they are not shared
