Abstract

LAB 4 HINAR HASSAN 03/08/2022
ABSTRACT : Given an Electrodynamic situation. Two charged plates,
separated by a
distance Y(meters), create an electric field, E which is measured as
the force
per unit charge(Newtons/Coulomb).A small positive charged particle,
Q(Coulombs)
is placed at the top plate and experiences a force, F(Newtons) which
creates an
acceleration, a(m/s^2) towards negative, it travels the full distance
Y.
The charge hits the negative plate at a velocity v, falling in a time
t..
Hitting with kinetic energy, K.
Equations governing the behavior are:
1. F=QE
2. a =F/m
3. y=1/2a(t^2)
4. v=at
5. K=1/2 m(v^2)

Determine the force experienced by a positively charged
particle, which is placed on the top of the positively charged
plate.It will then compute the acceleration. As the distance
etween the plates is fixed, it determines the time taken by the
particle to reach the negatively charged plate. Then computes the
velocity at which the particle collides. Finally, computes the
kinetic energy with which it collides on the negatively charged
plate.
