how do I involve the kinetic energy K in the equation?

How do you relate potential difference and electric potential energy ?

Think in terms of conservation of energy .

OR

Use Dimensional Analysis

Cici2017

work done equals to change in KENow what doesWork Kinetic Energy theoremsay ?

so Eqd=K

E=K/qd

Yeswork done equals to change in KE

so Eqd=K

E=K/qd
