Question

Intensity of an electric field (E) depends on distance r, due
to a dipole, is related as
(a) E α 1/r
(b) E α 1/r²
(c) E α 1/r³ (d) E α 1/r⁴

Answer 1

Answer:

please mark me as a brain list

Explanation:

Intensity of electric field due to a Dipole

E=

p

3cos

2

θ+1

⇒E∝

r

1

So, we can just dimensionally tell that Electric field will be inversely proportional to third power of r.
