Electric field due to a charged rod along its axis is given by

here we know that
L = 14 cm
r = distance from end of rod
r = 36 - 7 = 29 cm
Q = 222 mC
now we will have


<h2>The intensity of siren is 0.015 W m⁻²</h2>
Explanation:
The intensity of sound is inversely proportional to the square of distance between source and the observer .
Thus Intensity at a distance 25 m is I₁ ∝
I
Similarly the intensity at a distance 50 m is I₂ ∝
II
Dividing II by I , we have
=
=
= 
Thus I₂ =
x 0.06 = 0.015 W m⁻²
