Electric potential energy = qV= kqQ/d

Is this equal to the kinetic energy K?

 

[conscience]

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!

Now what does Work Kinetic Energy theorem say ?

 

[Cici2017]

Now what does Work Kinetic Energy theorem say ?

work done equals to change in KE

so Eqd=K

E=K/qd

 

[conscience]

work done equals to change in KE

so Eqd=K

E=K/qd

Yes

 

[Cici2017]

Yes

Thank you so much~
