An electron is released from rest at the negative plate of a parallel plate capacitor. the charge per unit area on each plate is σ = 1.69e-7 c/m2, and the plates are separated by a distance of 1.75e-2 m. how fast is the electron moving just before it reaches the positive plate?

Explanation:

Initial speed of the electron, u = 0

The charge per unit area of each plate,

Separation between the plates,

An electron is released from rest, u = 0

Using equation of kinematics,

..........(1)

Acceleration of the electron in electric field, ............(2)

Electric field, ............(3)

From equation (1), (2) and (3) :

v = 10840393.1799 m/s

or

So, the electron is moving with a speed of before it reaches the positive plate. Hence, this is the required solution.

because if the tool that you are using is not balanced it there would be false mass.

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
