What is the relationship between potential difference between the plates and electric field between the plates ?

How do you relate potential difference and electric potential energy ?

Think in terms of conservation of energy .

OR

Use Dimensional Analysis

Electric potential energy = qV= kqQ/d

Is this equal to the kinetic energy K?

Electric potential energy = qV= kqQ/d
No , this is for a point charge .

Cici2017
No , this is for a point charge .
Sorry, that's the only formula I know. Can you please tell me? Thank you!

If the electric field between the charged plates is E , what will be the force on the charged partice +q ?

F=Eq

Now if charged particle moves from positive plate to negative , how much is the work done on the particle by the electric force ?

W=Eqd

Now what does Work Kinetic Energy theorem say ?

Now what does Work Kinetic Energy theorem say ?
work done equals to change in KE

so Eqd=K

E=K/qd

work done equals to change in KE

so Eqd=K

E=K/qd
Yes

Cici2017
Yes
Thank you so much~
