Question

the potential difference between a and b in an uniform electric field is​

Answer 1

Hi friend here is your answer.

######################

We know V=Ed

So d= root over a^2+b^2 = distancebetween A and B.

And so V=E (a^2+b^2)

Answer 2

Answer:

1/4¶£(1/rb-1/ra)

Explanation:

Since it is the difference between electric potential between b and a.

Where ra means radius of a and rb means radius of b.

And other sign represent as usual.
