Question

in an uniform electric field of 20 v/m . find the potential difference of Vç – Và.
​

Answer 1

Answer:

a centimeter = 1 cm cm means

Answer 2

Answer:

-E.r

Explanation:

vc- va = vb- va

because vc=vb

vb- va = work done to shift any unit charge( slowly)

work done = -E . Δdr

let the distance between point a and b is r

vc-va = -E. r
