Question

If at a point, electric potential is zero, then what will be the potential difference ?

Answer 1

information is not sufficient
potential difference is measured between two points

Answer 2

Oh sorry!

I have : A point charge (at a point A) and a point P where electric potential is zero.

Answer 3

And I have to find electric potential for \(V_A\)

Answer 4

V_A in terms of U_A and U_P

SO, will U_P be equal to zero?

Answer 5

yeah

Answer 6

So if you have a point charge and somewhere ( P ) you don't 'feel' any electric potential than you must have b balancing force somewhere so that you don't 'feel' an effect.

Answer 7

so now, what would U_a be?

Answer 8

Well, I think that U_A = \(V_A\) q ?

Answer 9

correct! :-]

Answer 10

So, V_A should be equal to U_A/q

Answer 11

yes

Answer 12

and my book says that \(V_A = V_A - V_P = \cfrac{U_A - U_P}{q}\)

I know it will not make any difference to the original equation for V_A = U_A/q , if U_P =0 .

Answer 13

Oh okay. got it now.

Answer 14

Thanks @Miracrown and @Deepakrathee

Answer 15

you're welcome! ^^

Answer 16

ur welcome @mathslover

Answer 17

also they want to show that Electric potential is zero... which is why they wrote it that way.. but you can get from one to the other.

Answer 18

I wish you the best of luck as you study your electrostatics! ;-) @mathslover

Answer 19

Thanks Mira! I require more of that :0
